The editing spec doesn't mention editing non-HTML documents, and historically
this is only a feature that WebKit has supported. Supporting this feature
increases the attack surface of the browser without a clear benefit, so it
seems like a good idea to converge on this behaviour.

There are two related problems this patch is trying to address. The first, and
simpler, one is bug 1553436: there are websites that use existing variables and
functions named "u2f" and adding a non-replaceable readonly property with that
name on Window breaks them. The fix for this is straightforward: mark the
property [Replaceable].
The second problem, covered by bug 1551282, involves sites that use the Google
U2F polyfill. The relevant parts of that polyfill look like this:
'use strict';
var u2f = u2f || {};
u2f.register = some_function_that_only_works_right_in_Chrome;
u2f.sign = some_function_that_only_works_right_in_Chrome;
The failure mode for that code before this fix is that the assignment to "u2f"
throws because it's a readonly property and we're in strict mode, so any code
the page concatenates in the same file after the polyfill does not get run.
That's what bug 1551282 is about. The [Replaceable] annotation fixes that
issue, because now the polyfill gets the value of window.u2f and then redefines
the property (via the [Replaceable] setter) to be a value property with that
value. So far, so good.
But then we need to prevent the sets of u2f.register
and u2f.sign from taking effect, because if they are allowed to happen, the
actual sign/register functionality on the page will not work in Firefox. We
can't just make the properties readonly, because then the sets will throw due
to being in strict mode, and we still have bug 1551282. The proposed fix is to
make these accessor properties with a no-op setter, which is exactly what
[LenientSetter] gives us.
The rest of the patch is just setting up infrastructure for generating the
normal bits we would generate if "sign" and "register" were methods and using
that to create the JSFunctions at the point when the getter is called. The
JSFunctions then get cached on the u2f instance object.

According to the spec [1] 7.2.10.2, we should use the first line box's height or width as positioning unit to adjust box's position.
We will also use this value to adjust box when `snap-to-line` is false.
There, we implement a new chrome-only API to acquire this information, which would return the first line box's size in the `block` frame.

When adjusting cue's position, the goal is to place cue boxes fully inside the rendering area, and place in the right place.
In order to check whether the box is correctly inside the rendering area, we have to know the correct size of the cue box.
Therefore, we implement the new chrome-only APIs to acquire this information (box's height and width), and this returned value won't be affected by CSS transformation, which is good for positioning.

In this part, we pass along the navigation type (and index for when using the

top-level load "between" the start and end pages.
The patch might look a bit strange, since we're passing the navigation
operation to two places from RemoteWebNavigation.js (the normal message passing
that existed before this patch and the HangMonitor channel in this patch). This
is primarily to make it easier to stop passing the navigation info along the
HangMonitor channel once session history is uplifted into the parent process.
At that point, the check for whether there's a top-level load could happen in

https://github.com/whatwg/html/issues/3840#issuecomment-480894419
I think this is one of the sane behaviors we can have, what Blink / WebKit do
makes no sense to me.
Alternative potentially-sane behavior is making the initial value of the
stylesheet's disabled bit the same as the content attribute, and both reflect
and forward the attribute from the setter.
That means that setAttribute does something different than setting `disabled`,
which means that you can get into all sorts of funny states when reloading the
sheet... So I rather not do that.

This patch extracts two additional CompositorHitTestInfo flags from the
eDispatchToContent flag; eApzAwareListeners for elements that have
APZ-aware listeners, and eInactiveScrollframe for inactive scrollframe
or unlayerized scrollthumbs. The eDispatchToContent is then renamed to
eIrregularArea to reflect the fact that it is used for irregular-shaped
areas that require main-thread hit-testing.
Additionally, it is important to note that when using the non-WebRender
codepath, all three of these flags still end up gettings squashed into
the "dispatch to content" region on the EventRegions; when APZ
reconstructs a CompositorHitTestInfo it will turn anything in this
region back into an eIrregularArea. So this is a lossy round-trip
conversion for the non-WebRender case. However it should still result in
correct behaviour because the semantics of eIrregularArea result in APZ
relying on the main-thread to do hit-testing and so any APZ-aware
listeners and inactive scrollframes are also handled by the main-thread.

If user disables clipboard events, it means that they don't want to expose
clipboard data to web apps even if web apps cannot handle "paste" operation.
Therefore, they must not want to leak clipboard data with `InputEvent.data`
and `InputEvent.dataTransfer`.
This patch makes `InputEvent::GetData()` and `InputEvent::GetDataTransfer()`
returns empty string or new `DataTransfer` object which has only empty string
if:
- They are called by content JS.
- The event is a trusted event.
- `inputType` value is `insertFromPaste` or `insertFromPasteAsQuotation`.
The reason why we don't return null for both is, Input Events spec declares
`data` or `dataTransfer` shouldn't be null in the `inputType` values. And
the reason why we don't return empty `DataTransfer` is, web apps may expect
at least one data is stored in non-null `dataTransfer` value.
