Tasks dispatched from RunInStableState() can be cancelled if there's a load in
between, so this is not sound.
See nsSyncSection::IsCancelled().
This is the only patch in this bug that is worth uplifting IMO.

Now, we can get rid of `TextEditRules` and `HTMLEditRules` completely.
And also this patch renames their cpp files to `TextEditSubActionHandler`
and `HTMLEditSubActionHandler`.
`TextEditor::Init()` and `HTMLEditor::Init()` are still complicated due to
`AutoEditInitRulesTrigger`. The following patch will remove it.

`TextEditRules::DocumentIsEmpty()` is a wrapper of `TextEditor::IsEmpty()` so
that we can get rid of it simply.
`HTMLEditRules::DocumentIsEmpty()` needs to change. It's oddly checks only
`EditorBase::mPaddingBRElementForEmptyEditor` is `nullptr` or not. However,
the editor may be completely empty. And the result may be different from
`TextEditor::IsEmpty()` which is not overridden by `HTMLEditor`. For partially
solving this issue, this patch makes `HTMLEditor` overrides `IsEmpty()` and
optimizes `TextEditor::IsEmpty()`.
With this change, the caller of `HTMLEditRules::DocumentIsEmpty()` may behave
differently in the only caller, `HTMLEditor::SelectEntireDocument()`. And
unfortunately, its root called from `SelectAllCommand::DoCommand()`. However,
it does just collapse `Selection` into the root element (`<body>` or
`Document.documentElement`) if it returns `true`. Therefore, this change
must be safe since anyway `SelectionRefPtr()->SelectAllChildren()` with
the root element is exactly same as `SelectionRefPtr()->Collapse()` with
the empty root element if it's truly empty.

When we call nsContentUtils::IsPatternMatching, we swallow JS engine errors
unconditionally returning true.
This is bad, because if it happens in one of the value sets that arguably
shouldn't change the state of the element, we end up returning an arbitrary
value (true) which may or may not match the previous state of the element.
Handle error explicitly instead, by not updating the state.

We use `NotifyMediaStarted()` and `NotifyMediaStopped()` to notify `MediaControlService` on parent process to start/stop a media controller, and use `NotifyMediaAudibleChanged()` to notify controller's audible state in order to request audio focus.
As our goal is to use media controller to control media element, not for web audio, web speech and other stuffs which also use audio channel agent.
Therefore, we should notify parent process to start/stop controller only for media element, instead of sending a notification in AudioChannelService because that would create media controller for all different consumers which uses audio channel agent.

Spliting NotifyAudioChannelAgent() to StartAudioChannelAgent() and StopAudioChanelAgent() allows us to start and stop an AudioChannelAgent in a clear naming function, and to do related operation and checking every time we start/stop the agent.

This patch changes a few things about how nsFrameLoader is created, specifically
around the ChangeRemoteness API.
1. The private 'nsFrameLoader::nsFrameLoader' constructor has been simplified to
only have one overload, shared by the different `::Create` static methods.
2. The creation static method used by `ChangeRemoteness` has changed name to
`::Recreate`, as the signature is becoming more like the old method.
3. The `mNetworkCreated` bit is preserved when doing a `ChangeRemoteness`, as a
remoteness change shouldn't be affecting that property.
4. Unused fields are removed from the ChangeRemoteness API.
5. The `remoteType` attribute is now mandatory in the ChangeRemoteness API,
which simplifies the logic and makes it harder to accidentally misuse.

The CommonCreateWindow code requires having a BrowserHost for the tab that's
creating the window, which it tries to get from the requestor's BrowserParent.
For remote BrowserParents, though, there is no BrowserHost, so we need to get
it from the top-level embedder instead.

Most of our keyboard shortcut handling is handled by nsXBLWindowKeyHandler along
with nsXBLPrototypeHandler. With the impending removal of XBL this needs to
change.
This patch moves nsXBLWindowKeyHandler to dom/events/GlobalKeyListener and copies
nsXBLPrototypeHandler to dom/events/KeyEventHandler. Windows, text elements and
XUL <keyset> are changed to use the new copies and anything unnecessary for
those is stripped out.
XBL handler elements still remain using the existing nsXBLPrototypeHandler path.
Some of the code is ripped out there to make it compile. There is probably a
lot more that can be removed but since the whole of XBL is likely gone soon I'm
not sure it is worth cleaning that up much.

This is so that SetUseCounter is as cheap as possible.
This is in preparation for hooking the CSS use counters to telemetry. We want
CSS use counters to be fast and be propagated at once to the parent page. This
will make sure to use the same setup as everywhere else.
