Chrome does not allow nested `Document.execCommand()` calls:

On the other hand, Safari (and Firefox) allows it. However, it's worthwhile to
follow Chrome's behavior.
This patch makes `Document::ExecCommand()` return `false` when it's called

This is exactly same behavior, and we should watch broken web apps reports

And this patch sets the pref to `true` when all crash tests under

I thought this would fix <input type=number style="user-select: none">, but

<input type=number> doesn't have the editor root as a root of the anonymous

editable flag. So tweak the code a bit to handle stuff in a simpler way than
setting the flags after the fact, and set the NAC-root flag earlier to avoid
the mOuterWrapper->AppendChildTo(root) call forgetting about root's flags.
I had to tweak one AccessibleCaret test, but that's because it uses <textarea>

I refactored the dragdrop tests to cover more input types, but I ended up not

`UIEvent::GetRangeParent()` retrieves `nsIContent` instance but it needs to

`nsIContent` is better type in C++ code. Therefore, this patch renames it
to `UIEvent::GetRangeParentContent()` and makes new `UIEvent::GetRangeParent()`

Additionally, some callers call `UIEvent::RangeOffset()` too, but that means
that they compute same things twice because both of them use
`nsLayoutUtils::GetContainerAndOffsetAtEvent()` with same input arguments.
Thus, `UIEvent::GetRangeParentContent()` should also return offset with optional
out argument. (Note that this does not make `RangeOffset()` use
`GetRangeParentContent()` because using out parameter for range parent causes
unnecessary computation cost for `RangeOffset()`.)
Therefore, finally, `UIEvent::GetRangeParentContent()` becomes also an alias of
raw method `UIEvent::GetRangeParentContentAndOffset()` which also returns offset
with out argument.

`AutoEditActionDataSetter` is created in the stack when editor's public method
is called and that guarantees lifetime of global objects in editor such as
editor itself, selection controller, etc.
The dispatcher of `beforeinput` event returns `NS_ERROR_EDITOR_ACTION_CANCELED`
if an event is actually dispatched but canceled. The reason why it's an error
is, editor code must stop handling anything when any methods return error.
So, returning an error code is reasonable in editor module. But when it's
filtered by `EditorBase::ToGenericNSResult()` at return statement of public
methods, it's converted to `NS_SUCCESS_DOM_NO_OPERATION`. This avoids throwing
new exception, but editor class users in C++ can distinguish whether each edit
action is canceled or handled. The reason why we should not throw new
exception from XPCOM API is, without taking care of each caller may break some
our UI (especially for avoiding to break comm-central). Therefore, this patch
does not make XPCOM methods return error code when `beforeinput` event is
canceled.
In most cases, immediately after creating `AutoEditActionDataSetter` is good
timing to dispatch `beforeinput` event since editor has not touched the DOM
yet. If `beforeinput` requires `data` or `dataTransfer`, methods need to
dispatch `beforeinput` event after that. Alhtough this is not a good thing
from point of view of consistency of the code. However, I have no better
idea.
Note 1: Our implementation does NOT conform to the spec about event order
between `keypress` and `beforeinput` (dispatching `beforeinput` event after
`keypress` event). However, we follow all other browsers' behavior so that it
must be safe and the spec should be updated for backward compatibility.
Spec issue: https://github.com/w3c/uievents/issues/220

Some HTML editor command classes call `*AsAction()` methods multiple times.
That causes that user needs multiple undo/redo for a command and one command
causes multiple "input" events. For both compatibility with the other
browsers and making "beforeinput" cancelable, they should call `*AsAction()`
once. Instead, `HTMLEditor` should handle related element deletion.
This patch makes `HTMLEditor::RemoveInlinePropertyInternal()` remove multiple
elements if its caller allows, and `HTMLEditor::SetInlinePropertyAsAction()`
call `RemoveInlinePropertyInternal()` in some cases.
According to comm-central and BlueGriffon, we can make
`HTMLEditor::RemoveInlineProperty()` also removes the related methods
automatically because comm-central does same thing from script and BlueGriffon
does not use this. However, we cannot do that for
`HTMLEditor::SetInlineProperty()` because BlueGriffon may call it with any

`AutoEditActionDataSetter` is created in the stack when editor's public method
is called and that guarantees lifetime of global objects in editor such as
editor itself, selection controller, etc.
The dispatcher of `beforeinput` event returns `NS_ERROR_EDITOR_ACTION_CANCELED`
if an event is actually dispatched but canceled. The reason why it's an error
is, editor code must stop handling anything when any methods return error.
So, returning an error code is reasonable in editor module. But when it's
filtered by `EditorBase::ToGenericNSResult()` at return statement of public
methods, it's converted to `NS_SUCCESS_DOM_NO_OPERATION`. This avoids throwing
new exception, but editor class users in C++ can distinguish whether each edit
action is canceled or handled. The reason why we should not throw new
exception from XPCOM API is, without taking care of each caller may break some
our UI (especially for avoiding to break comm-central). Therefore, this patch
does not make XPCOM methods return error code when `beforeinput` event is
canceled.
In most cases, immediately after creating `AutoEditActionDataSetter` is good
timing to dispatch `beforeinput` event since editor has not touched the DOM
yet. If `beforeinput` requires `data` or `dataTransfer`, methods need to
dispatch `beforeinput` event after that. Alhtough this is not a good thing
from point of view of consistency of the code. However, I have no better
idea.
Note 1: Our implementation does NOT conform to the spec about event order
between `keypress` and `beforeinput` (dispatching `beforeinput` event after
`keypress` event). However, we follow all other browsers' behavior so that it
must be safe and the spec should be updated for backward compatibility.

Chrome moves focus to dropped element or editing host containing dropped
element, but we don't do it. For compatibility with Chrome, it's better to
follow their behavior. Additionally, this fixes 2 issues. One is, when
dropping something into non-focused contenteditable element, we've failed to
initialize selection from `TextEditor::PrepareToInsertContent()` because
`pointToInsert` is outside of selection limiter if another editing host
has focus. The other is, when same case, we've failed to insert dropped
content because edit action handlers of `HTMLEditor` check whether editing
position is in active editing host.
Finally, this patch makes `TextEditor::OnDrop()` cancels to dispatch "input"
event if it fails something before trying to insert dropped content. Without
this change, `EditorBase::DispatchInputEvent()` tries to dispatch without
proper `data` or `dataTransfer` and that hits `MOZ_ASSERT` in `nsContentUtils`.
Additionally, this fixes an existing bug which `HTMLEditor` may insert `\r`

Finally, `Document.execCommand()` still does not work fine if selection
starts from very start of block and/or end at very end of block because
`PromoteInlineRange()` extends selection range to contain the
containers, then, `SubtreeContentIterator` won't list up text nodes.
In this case, `RemoveInlinePropertyInternal()` expects that
`RemoveStyleInside()` removes text node style with creating
`<span>` elements. However, `RemoveStyleInsilde()` only handles
`Element`s and it handles elements from most-descendants.
Therefore, it cannot distinguish whether text node style comes
from removing inline elements or parent block.
This patch makes `RemoveInlinePropertyInternal()` collect
descendant text nodes in the range after handling all nodes in
the range except descendant text nodes, then, check the
final style of descendant text nodes, finally, remove the style
if coming from parent block.

If selection range is not in **one** text node, `RemoveInlinePropertyInternal()`
collects target nodes with `SubtreeContentIterator`. It only collects topmost
nodes which are **entirely** contained in the range (it's enough because their
descendants will be handled by `RemoveStyleInside()` recursively).
The reasons why it uses `SubtreeContentIterator` rather than
`PreContentIterator` must be:
1. Performance reason.
2. Assuming there are no multiple text nodes.
3. Not expects that user removes text node styles come from parent block.
The reason 2 is wrong because when removing a style, all browsers don't
join text nodes which was in removing element with adjacent text nodes.
(I.e., we cannot change this behavior for compatibility.)
The reason 3 is of course wrong we're struggling with this scenario.
Therefore, `RemoveInlinePropertyInternal()` needs to collect partially
selected text nodes by itself (if there are). Then, we can merge the
single text node selected case with the `for` loop.

it does just collapse `Selection` into the root element (`<body>` or

Surprisingly, `handled` is set to `false` only when there is an error or
there is no selection range. Therefore, this long block has already been

excption.
