First half of `HTMLEditoRules::GetListActionNodes()` does 2 things. One is
trying to get parent list element of `Selection` ranges if `aEntireList` is
`EntireList::yes`. If it found a list element, it does nothing anymore.
Otherwise, falls backs to `EntireList::no` case. So, if each caller which
calls it with `EntireList::yes`, `GetListActionNodes()` does not need the
argument. Therefore, this patch does it first.
Then, `GetListActionNodes()` calls
`CollectEditTargetNodesInExtendedSelectionRanges()` or
`SplitInlinesAndCollectEditTargetNodesInExtendedSelectionRanges()`. It's
considered with `aTouchContent` is `yes` or `no`. So, this should be done
by each caller for making it clearer.

This patch includes a logic change. `HTMLEditRules::mListenerEnabled` is used
for storing 2 state. One is that whether `HTMLEditRules` can handle the legacy
listener methods (they came from `nsIEditActionListener`) with `mHTMLEditor` or
not. The other is that whether current edit sub-action handler temporarily
disables the listeners for performance or not.
For the former, we can check same result with `HTMLEditRules::mInitialized`

However, the latter, current design is obviously wrong. Currently,
`HTMLEditRules::mListenerEnabled` is set only to `false` temporarily from

which are nested by mutation event listeners. So, currently,

When browsing reported site (https://minecraft.curseforge.com/), user that uses Android cannot set caret on some editable contents.
GV's IME code uses `NOTIFY_IME_OF_SELECTION_CHANGE` to update selection on native IME. But GV doesn't receives this notification on this reported site. This notification is fired by editor's selection listener, but when this occurs, this notification is no logner fired unfortunately. Because selection listener isn't registered by current selection.
At first, editor registers selection listener by `EditorBase::Init`. But like test case, if PresShell is destroyed after editor is created, this registration is no longer used, and we have to register it by new selection again. So we should tear down editor when PresShell is destroyed. (or we have to add a way to re-initialize selection listener?)
This isn't related to Android. Android's IME code depends on this notification, so this occurs easily.
Also, `PresShell::SetCaretEnabled` only works when caret is valid (`PresShell::GetCaret` has caret). If caret is nothing, it hits assertion.

The exception is that StaticPrefsAll.h, which is equivalent to StaticPrefs.h,
and is used in `Codegen.py` because doing something smarter is tricky and
suitable for a follow-up. As a result, any change to StaticPrefList.yaml will

Unmasking is an optional style of showing password. Therefore, if callers of
`nsIEditor::Unmask()` specify middle of surrogate pair(s), it may mean that
they want to expand the unmask range from shorter range which does not include
the high and/or low surrogate. Therefore, one of the surrogates is in unmasked
range, we unmask the surrogate pair. However, we handle this in a lot of
places, i..e., we have duplicated code. This can get rid of these duplicates
with making `nsIEditor::Unmask()` expand the range automatically.

This patch creates editor API to get/set unmask-range of password field.
Its design is similar to `setSelectionRange()` and `selectionStart`/
`selectionEnd` attributes. The unmasked range is automatically
masked if `aTimeout` of `unmask()` is set to non-zero.
Otherwise, unmasked range won't be masked automatically even after user
or web apps modifies the editor, and inserting new character expands
unmasking range.
The following patch makes `TextEditRules` use these API to implement
delayed masking of password.
Note that editor has never supported dynamic `eEditorPasswordMask` change.
E.g., if you have typed some characters into an editor and toggle the flag,
the characters are not unmasked nor masked. Then, if you type new characters,
only they are correctly masked or unmasked. This patch puts `MOZ_ASSERT()`
to reject this feature completely on debug build for making the unmasking

Since JSWindowActors don't have direct access to synchronous messaging,
ChromeScript callers are going to need to migrate to asynchronous messaging
and queries instead.
Since there's no comparable API to sendQuery for frame message managers, this
patch adds a stub that uses synchronous messaging, but makes the API appear
asynchronous, and migrates callers to use it instead of direct synchronous
messaging. This will be replaced with a true synchronous API in the actor
migration.
Fortunately, most of the time, this actually leads to simpler code. The
`sendQuery` API doesn't have the odd return value semantics of
`sendSyncMessage`, and can usually just be used as a drop-in replacement. Many
of the `sendSyncMessage` callers don't actually use the result, and can just
be changed to `sendAsyncMessage`. And many of the existing async messaging
users can be changed to just use `sendQuery` rather than sending messages and
adding response listeners.
However, the APZ code is an exception. It relies on intricate properties of
the event loop, and doesn't have an easy way to slot in promise handlers, so I
migrated it to using sync messaging via process message managers instead.

The SpecialPowers set*Pref/get*Pref APIs currently use synchronous messaging
to set and get preference values from the parent process. Aside from directly
affecting callers of those APIs, it also affects callers of `pushPrefEnv`,
which is meant to be asynchronous, but is in practice usually synchronous due
to the synchronous messaging it uses.
This patch updates the getPref APIs to use the in-process preference service
(which most callers are expecting anyway), and also updates the callers of
the setPref and pushPrefEnv APIs to await the result if they're relying on it
taking effect immediately.
Unfortunately, there are some corner cases in tests that appear to only work
because of the quirks of the current sync messaging approach. The synchronous
setPref APIs, for instance, trigger preference changes in the parent
instantly, but don't update the values in the child until we've returned to
the event loop and had a chance to process the notifications from the parent.
The differnce in timing leads some tests to fail in strange ways, which this
patch works around by just adding timeouts.
There should be follow-ups for test owners to fix the flakiness.

`EditorCommand::DoCommandParam(Command aCommand, TextEditor& aTextEditor)`,
which just delegates to `DoCommand()`.
This patch adds some undeclared commands but which are handled by
`EditorCommand` subclasses, and changes `CommandInt` type from `int8_t` to
`uint8_t` since the count of `Command` items becomes over 128.

`nsIDocumentStateListener` is a scriptable interface and each method may run
any script. So, we should mark them as `can_run_script`. Then, we need to
mark a lot of editing methods because we need to mark
`EditorBase::EndTransactionInternal()` and `EditorBase::DoTransactionInternal()`
as `MOZ_CAN_RUN_SCRIPT`.

This seems to be regression by bug 1362858.
Actually, single quotation mark is always separator for spellchecker after
landing bug 1462858. When user tries to input "doesn't", "'" becomes separator
for spellchecker. Then "doesn" will be misspell word.
So we shouldn't mark single quotation mark as separator if user is inputting
word.

It'd be better to change copy constructor of `EditorDOMPointBase` to explicit,
but it'd require too many changes in editor code. So, this patch just changes
each method callers only.

For guaranteeing the sets of container node, offset in it, and the node
referred by the offset, the method should use `EditorDOMPoint` instead of
managing them separately.

This is a simple mistake of `MOZ_ASSERTION()` in it. When `mParent` is a node
which can have children, `mChild` should be non-`nullptr` or `mOffset` should
/ be set to the end of `mParent`. But when `mParent` is not a container, any
`mOffset` value should be allowed.

As far as I've tested, `TextEditor` has the following structure patterns:
1. If it's for a non-empty `<input>` element, it has only one text node.
2. If it's for an empty `<input>` element, it has only bogus node.
3. If it's for a non-empty `<textarea>` element, it has a text node and
`moz-<br>` element. Additionally they are followed by `<scrollbar>` and
`<resizer>` elements.
4. If it's for an empty `<textarea>` element, it has a `moz-<br>` element
followed by `<scrollbar>` and `<resizer>` elements.
Additionally, `TextEditRules::WillInsert()` always removes bogus node if
there is. So, in the case #2, there is no children.
Fortunately, we don't support XUL addons anymore on Firefox. However, in
other products like Thunderbird, the tree may be changed as unexpected.
Therefore, we still need to keep checking the tree, but we can use the fast
path for `<textarea>` element too.

This patch makes editors return new error code internally when clipboard event
is dispatched and canceled by script. This is for making each caller stop
handling the edit action. However, it's not actual failure. Therefore, making
public methods return `NS_SUCCESS_DOM_NO_OPERATION` instead via
`EditorBase::ToGenericNSResult()`.

Currently, this bug does not occur actually because nobody has not accessed
these command classes directly and they are registered only in command table
for HTML editor. However, once rewriting `nsHTMLDocument::ExecCommand()` with
these classes, its `IsCommandEnabled()` should return false if given editor
is `TextEditor`. The reason why we need this fix is, when we make
`ExecCommand()` call `IsCommandEnabled()` and it returns `true`, `ExecCommand()`
needs to call `DoCommand()`. Then, it throws exception if given editor is not
an `HTMLEditor` but the command class is only for `HTMLEditor`.
This patch adds new WPT for testing whether `document.execCommand()` works
with `<input>` and `<textarea>`. The behavior has not been standardized, but
Chromium handles some commands even in it. So, I write the expectations from
the point of view of web developers. (Chrome fails in "cut", "copy" and
"removeformat" cases.)

A test was intermittently crashing because it was calling
restoreNormalRefresh after closing the window. This meant
LayerTransactionParent::RecvLeaveTestMode fired after the
CompositorBridgeParent had been destroyed.
This fixes the test by calling restoreNormalRefresh before
win.close. It also checks mDestroyed in RecvLeaveTestMode (for both
LayerTransactionParent and WebRenderBridgeParent).

Note that `DoCommand()` of some command classes have not returned error when
