Summary: Really sorry for the size of the patch. It's mostly automatic
s/nsIDocument/Document/ but I had to fix up in a bunch of places manually to
add the right namespacing and such.
Overall it's not a very interesting patch I think.
nsDocument.cpp turns into Document.cpp, nsIDocument.h into Document.h and
nsIDocumentInlines.h into DocumentInlines.h.
I also changed a bunch of nsCOMPtr usage to RefPtr, but not all of it.
While fixing up some of the bits I also removed some unneeded OwnerDoc() null
checks and such, but I didn't do anything riskier than that.
Summary:
The latest version of Gecko doesn't crash by this HTML, but I would like to add
this for the future.

After fixing bug 1427060, HTMLEditor treats attribute of style as nullptr.
However, if empty string is used to call NS_Atomize(), it returns
nsGkAtoms::_empty. Therefore, HTMLEditor fails to check whether attribute is
specified or not with nullptr check since some root callers sets
nsGkAtoms::_empty instead of nullptr.
This patch makes HTMLEditor always use nullptr for empty string of attribute
of style with wrapping NS_Atomize() with AtomzieAttribute(). Additionally,
for safer change, this patch makes PropItem and TypeInState treat
nsGkAtom::_empty as nullptr.

Storage events are fired either directly after getting response from synchronous SetItem call or through observers. When a new onstorage event listener is added, we sycnhronously register an observer in the parent process. There's always only one observer actor per content process.
PBackgroundLSDatabase is now managed by a new PBackgroundLSObject protocol. PBackgroundLSObject is needed to eliminate the need to pass the principal info and document URI everytime a write operation occurs.
Preparation of an observer shares some states with preparation of a datastore, so common stuff now lives in LSRequestBase and preparation of a datastore now implements a nested state machine.
This patch was enhanced by asuth to drop observers only when the last storage listener is removed.
EventListenerRemoved is invoked on any removal, not just the final removal, so we need to make sure it's the final removal before dropping observer.
The implementation is based on a cache (datastore) living in the parent process and sync IPC calls initiated from content processes.
IPC communication is done using per principal/origin database actors which connect to the datastore.
The synchronous blocking of the main thread is done by creating a nested event target and spinning the event loop.
Turn all const lists and related attributes into cenums, to provide a
vague sense of type safety.

There's a few subtle behavior changes here, which I'll try to break down in the
commit message.
The biggest one is the EditableDescendantCount stuff going away. This
was added in bug 1181130, to prevent clicking on the non-editable div from
selecting the editable div inside. This is problematic for multiple reasons:
* First, I don't think non-editable regions of an editable element should
be user-select: all.
* Second, it just doesn't work in Shadow DOM (the editable descendant count is
not kept up-to-date when not in the uncomposed doc), so nested
contenteditables behave differently inside vs. outside a Shadow Tree.
* Third, I think it's user hostile to just entirely disable selection if you
have a contenteditable descendant as a child of a user-select: all thing.
WebKit behaves like this patch in the following test-case (though not Blink):
https://crisal.io/tmp/user-select-all-contenteditable-descendant.html
Edge doesn't seem to support user-select: all at all (no pun intended).
But we don't allow to select anything at all which looks wrong.
* Fourth, it's not tested at all (which explains how we broke it in Shadow DOM
and not even notice...).
In any case I've verified that this doesn't regress the editor from that bug. If
this regresses anything we can fix it as outlined in the first bullet point
above, which should also make us more compatible with other UAs in that
test-case.
The other change is `all` not overriding everything else. So, something like:
<div style="-webkit-user-select: all">All <div style="-webkit-user-select: none">None</div></div>
Totally ignores the -webkit-user-select: none declaration in Firefox before this
change. This doesn't match any other UA nor the spec, and this patch aligns us
with WebKit / Blink.
This in turn makes us not need -moz-text anymore, whose only purpose was to
avoid this.
This also fixes a variety of bugs uncovered by the previous changes, like the
SetIgnoreUserModify(false) call in editor being completely useless, since
presShell->SetCaretEnabled ended in nsCaret::SetVisible, which overrode it.
This in turn uncovered even more bugs, from bugs in the caret painting code,
like not checking -moz-user-modify on the right frame if you're the last frame
of a line, to even funnier bits where before this patch you show the caret but
can't write at all...
In any case, the new setup I came up with is that when you're editing (the
selection is focused on an editable node) moving the caret forces it to end up
in an editable node, thus jumping over non-editable ones.
This has the nice effect of not completely disabling selection of
-moz-user-select: all elements that have editable descendants (which was a very
ad-hoc hack for bug 1181130, and somewhat broken per the above), and also
not needing the -moz-user-select: all for non-editable bits in contenteditable.css
at all.
This also fixes issues with br-skipping like not being able to insert content in
the following test-case:
<div contenteditable="true"><span contenteditable="false">xyz </span><br>editable</div>
If you start moving to the left from the second line, for example.
I think this yields way better behavior in all the relevant test-cases from bug
1181130 / bug 1109968 / bug 1132768, shouldn't cause any regression, and the
complexity is significantly reduced in some places.
There's still some other broken bits that this patch doesn't fix, but I'll file
follow-ups for those.

Currently, a lot of code dispatch "input" event and some of them dispatch

creates nsContentUtils::DispatchInputEvent() to make all of them dispatch
correct event.
Unfortunately, due to bug 1506439, we cannot set pointer to refcountable
classes of MOZ_CAN_RUN_SCRIPT method to nullptr. Therefore, this patch
creates temporary RefPtr<TextEditor> a lot even though it makes damage to
the performance if it's in a hot path.
This patch makes eEditorInput event dispatched with
InternalEditorInputEvent when "input" event should be dispatched with
dom::InputEvent. However, this patch uses WidgetEvent whose message is
eUnidentifiedEvent and setting WidgetEvent::mSpecifiedEventType to

Even when execCommand("insertorderedlist") and

Fortunately, the XPCOM method is used only for handling
execCommand("insertorderedlist") and execCommand("insertunorderedlist") on
Firefox. Therefore, we should make it set EditAction to
EditAction::eRemoveOrderedListElement or EditAction::RemoveUnorderedListElement.
Note that comm-central uses this method directly and uses "cmd_removeList"
which causes calling the XPCOM method with empty string. However, input
events for them won't be exposed to the web. Therefore, it's okay to set

Both Chrome and Safari dispatches 2 sets of "beforeinput" and "input" events
when user drag and drop content in same editor. One is "deleteByDrag" and
the other is "insertFromDrop". We need to follow same behavior since
it should be able to cancel only "deleteByDrag" or "insertFromDrop" when
we implement "beforeinput" event.
HTMLEditor::InsertObject() may handle asynchronously. And we don't need to
do anything additionally for HTMLEditor. Therefore, TextEditor::OnDrop()
can delete selection before inserting dropped content by itself.
Therefore, this patch makes TextEditor::OnDrop() call
TextEditor::PrepareToInsertContent() and EditorBase::FireInputEvent() by
itself.
Unfortunately, it seems that we cannot write automated tests for this.
Even if using synthesizeMouse() of EventUtils, synthesizing mouse events
won't generate "dragover" nor "drop" events. Perhaps, like EventUtils.js,
we need to do something with drag service, but it means that we cannot

TextEditor::InsertFromDataTransfer() calls only TextEditor::InsertTextAt()
and TextEditor::InsertTextAt() calls only TextEditor::InsertTextAsSubAction() if
insertion point is nullptr. Therefore, if the callers sets nullptr, they
should call TextEditor::InsertTextAsSubAction() directly. Then, we can

HTMLEditor::InsertFromDataTransfer() calls HTMLEditor::InsertObject(),
HTMLEditor::DoInsertHTMLWithContext() or TextEditor::InsertTextAt().
HTMLEditor::InsertObject() calls HTMLEditor::DoInsertHTMLWithContext()

Unfortunately both HTMLEditor::InsertObject() and
HTMLEditor::DoInsertHTMLWithContext() are called by

we cannot make them require non-nullptr insertion point, though, anyway,

When Selection is NOT collapsed, we remove selected content. Therefore,
web apps don't need to know range information of user operation. However, web
apps may want to know direction of the operation (backward or forward). E.g.,
web apps may just mark selected range as "deleted" and move caret before or
after the range.
Therefore, when computed EditAction is eDeleteWordBackward or
eDeleteToBeginningOfSoftLine, we should use eDeleteBackward instead. When it
is eDeleteWordForward or eDeleteToEndOfSoftLine, we should use eDeleteForward
instead.
Note that only on Windows, we follow behavior of richtext control (and Word).
That is, Ctrl + Backspace/Delete collapse from start of selected range to
start/end of current word. I.e., collapsing Selection to start first and
removing to start or end of current word is Windows's standard behavior.
Currently, we do this in DeleteSelectionAsSubAction() but every caller
specifies eNone to aDirection except DeleteSelectionAsAction(). So, we can
move this before re-computing EditAction in DeleteSelectionAsAction().

Input Events Level 2 declares "deleteByComposition" for empty composition
removes selected content and "deleteCompositionText" for canceling composition.
https://w3c.github.io/input-events/#interface-InputEvent-Attributes
Therefore, TextEditor::OnCompositionChange() should use a new EditAction for
the former only when new composition string is empty, there is no composition
string and there is non-collapsed Selection.
And also TextEditor::OnCompositionEnd() should use another new EditAction for
the latter when composition is canceled with empty string (we don't restore
selected content which is removed by the composition).
Additionally, due to bug 1305387, we don't dispatch "input" event when
we handle TextEditor::OnCompositionChange(). Instead, we dispatch it
when we handle TextEditor::OnCompositionEnd(). Therefore, we need to
use EditAction::eCommitComposition in TextEditor::OnCompositionEnd().

error even when it does not find a cell element. Finally, copies each
CellData member to the variable which received corresponding value from
GetCellDataAt() for making this change safe. Note that for easier to review,

nsITableEditor::GetCellDataAt() is an XPCOM method but used internally a lot.
Additionally, it scatters a lot of variables (including unused) since it takes

This does not replaces the callers yet since it's too risky if the caller is
not tested by automated test. Following patches will replace the method call
and each variable step by step.

This patch makes EventStateManager handle middle click paste as a default
action.
Unfortunately, we cannot remove the call of HandleMiddleClickPaste() in
EditorEventListener because it's important to consume middle click event
before any elements in the editor. For example, if clicked HTMLEditor has
non-editable <a href> element, middle click event needs to be handled by the
editor rather than contentAreaUtils which handles click events of <a href>
elements. The cause of this kind of issues is, any click event handlers
which handle non-primary button events still listen to "click" events.
Therefore, this patch makes HandleMiddleClickPaste() do nothing if the mouseup
event is fired on an editor.
Differential Revision: https://phabricator.services.mozilla.com/D7855

extra : moz-landing-system : lando
This is preparation of the last patch. Even if no editor is clicked with
middle button, we need to do:
- collapse Selection at the clicked point.
- dispatch "paste" event.
Therefore, HandleMiddleClickPaste() should dispatch ePaste event by itself
and each editor methods should have a bool argument which the caller wants
ePaste event automatically.
Note that Chromium dispatches "paste" event and pastes clipboard content
into clicked editor even if preceding "auxclick" event is consumed.
However, our traditional behavior is not dispatching "paste" event nor
pasting clipboard content. Unless Chromium developer keeps their odd
behavior, we should keep our traditional behavior since our behavior is
conforming to DOM event model.

The ancestor limiter is set by focus event handler of editor. But window that
is run script has no focus, this event isn't fired by addRange etc.
Some execCommand's commands such as 'forwardDelete' uses WillDeleteSelection
then selection for deletion is set by selection controller (in
TextEditor::ExtendSelectionForDelete). So, due to no ancestor limiter, caret
(and any for delete commands such as CharacterExtendForDelete) can move to out
of editor's root.
So we should set ancestor limiter if nothing. If focus event is received by
