Feeding a media element with the captured stream from the same media element does not make sense. Currently the spec does not mention anything about it. I'll clarify the case in the spec. In the meantime, when a cycle is detected, the setting of the `srcObject` is ignored and a warning is produced in the console.

There's no use case for stateful comparators, so they can be just plain
function pointers.
This is used in some hot places like CSS selector matching.

In favor of the NativeAnonymous versions which they forward to.
Done automatically with:
rg -l 'IsInAnonymousSubtree' | xargs sed -i 's/IsInAnonymousSubtree/IsInNativeAnonymousSubtree/g'

In order to test its parsing and serialization, we expose it but protect
it behind a pref.
Besides, I would like to drop layout.css.aspect-ratio-number.enabled in
the next patch because the spec has been updated. It seems we don't have
to keep this pref and we should always use Number.

This patch will do :
- update the media status when media changes its owner browsing context
The advantage of doing so :
- make the media status in `ContextMediaInfo` correcly
More details :
`ContextMediaInfo` stores the media status of each browsing context, but actually the media doesn't always need to stay in one browsing context. We can move it to other browsing contexts (iframe) by appending it to other browsing context's document body.
For example, in [1], we move the video from the main frame to another iframe.
Therefore, when we move the media to a new browsing context, we should also update its media status (controlledMedia/playing/audio number) for its previous owner browsing context.

This patch will do :
- remove audible check from the logic of registering controller
- include audio channel affect on the media element's audible state
The advantage of doing so :
- it can help to reduce the intermittent failure during testing by earlier hooking media elements in the content process to the media controller in the chrome process
More details :
In D72497, we have added the audible check to postpone the activation of the media controller, which would ensure that we only control media after it become audible. Therefore, we can remove the previous implementation which we use to achieve that in media element.
When having that audible check in media element, it would postpone the timing of adding media element to `ContentMediaController` that causes some intermitent failures when I was writing test for bug1633565. When removing those checks, we can ensure that the media element would have always been added into `ContentMediaController` after calling `video.play()`. If the element haven't been added into `ContentMediaController`, then it would miss to handle the media key events when test generates a fake media key event, which causes an intermitent failure.

Per https://html.spec.whatwg.org/#selector-read-write:
> The :read-write pseudo-class must match any element falling into one
> of the following categories [...]:
>
> * input elements to which the readonly attribute applies, and that
> are mutable (i.e. that do not have the readonly attribute
> specified and that are not disabled)
>
> * textarea elements that do not have a readonly attribute, and
> that are not disabled.
>
> * elements that are editing hosts or editable and are neither
> input elements nor textarea elements.
This fixes the `:disabled` bits.
This matches Safari behavior and the spec, but not Chrome, which has our
behavior.
Fix the WPT, which had multiple issues, as :read-only is defined to be
just the opposite of :read-write. This will pass as soon as I unprefix
the pseudo-class.

In RFP mode, canvas image extraction leads to an all-white image, replace that
with a random (sample 32 bytes of randomness and fill the buffer with that)
'poison pill'. This helps defeat naive fingerprinters by producing a random
image on every try. This feature is toggled using a new, default on, pref
`privacy.resistFingerprinting.randomDataOnCanvasExtract`.
Updated `browser_canvas_fingerprinting_resistance.js` to test this new feature
as well.
Updates and replaces D66308.

This should make it easier to write tests for race-conditions, as
the resolving value now indicates which event was received.
This required updating a test which for some reason asserted
undefined being the resolving value, as a way of "testing" if the
Promise resolved at all. Since await already throws Errors when it
is rejected, and the test throws a timeout if it doesn't resolve in
time, this assertion was removed. It did not add any value.
