gfxFontCache acquires and releases its mutex during various operations.
In order to keep the state internally consistent, we should only release
the lock after the full operation is complete. This involves moving the
deletion of gfxFont to outside the lock via a temporary discard array.
The expiration state should not be protected by the gfxFont's mutex
since we don't hold it during most operations. Instead we should hold
gfxFontCache's mutex because then we can guarantee the operation is
atomic, particularly when a worker wants a font, and the main thread is
aging the generations.
When a font is returned from gfxFontCache, we now return it already
removed from the tracker, and with its refcount updated. This avoids any
potential races between the expiration timer and a worker accessing the
font, as well as simplying the callers so they don't need to be aware of
addref-ing manually in case the result is to be discarded (so that it
gets readded to the tracker).

A disabled form controls cannot be focused, and its frame selection is different
from the one for not-editable content. Use GetLastFocusedFrameSelection() (added
in Bug 253870) to get the correct frame selection that is visible to the user.
Add some basic tests for disabled <textarea> such as long pressing to select,
dragging, etc. They should behave the same as normal <textarea>.

All its members are optional, so we can just use it as a plain struct
rather than Maybe<> all around, which simplifies the code and prevents
silly bugs like bug 1779592.
Mostly automatic via:
rg -l 'SVGImageContext' . | xargs sed -i 's/Maybe<SVGImageContext>/SVGImageContext/g'
With trivial build fixes.
Not intended to change behavior.

That was about XBL constructors being able to run script. But XBL is
gone and this should just be wasted work.
I want to land this in preparation for container queries substantially
changing the model here.

When something switches to display: none, right now we rely on
StopAnimationsForElementsWithoutFrames(), which posts a restyle and the
previous ProcessPendingRestyles call was papering over it.
For other elements in the display none subtree it doesn't matter,
because we don't keep their styles around, but for the display: none
element themselves we do need to update transitions on time.
We could, possibly more generally, remove
StopAnimationsForElementsWithoutFrames() altogether and cancel
animations when we clear style data, perhaps... But that's probably
worth a follow-up.

I don't think why we have a mobile stylesheet (IIUC Android doesn't have
tooltips...), but I noticed that most tooltip styles are the same and it
should be doable to just unify them in xul.css.
We can't keep the platform-specific bits on their own stylesheet because
it loads _before_ xul.css, and thus overrides wouldn't quite do.
Depends on D151640

Even we don't have internal aliases right now (and that seems a bit
silly) we do have pref-gated aliases. An alias ID passed to IsEnabled
with the wrong EnabledState would misbehave, assert, and crash.
Though we don't have such callers in the tree because InspectorUtils
passes only arguments that make us not look at the flags, it seems more
reliable this way.

So we can specify the keyframe-specific composite operation. However,
these is a spec issue about the default composite for CSS Animations:
https://github.com/w3c/csswg-drafts/issues/7476.
I choose to use auto as the default composite for missing keyframes to match
the definition in web-animations-1 because I think this makes more sense:
> If the keyframe-specific composite operation for a keyframe is not set, the
> composite operation specified for the keyframe effect as a whole is used for
> values specified in that keyframe.

Let nsAnimationManager takes animation-composition into account.
Note: This doesn't support animation-composition on each keyframes.

This patch introduces animation-composition longhand but we don't
accept it in @keyframe rule for now. I will support this for @keyframe
in the patch series.
Besides, the shorthand of animation doesn't include animation-composition.
The spec issue is: https://github.com/w3c/csswg-drafts/issues/6946.
We could fix the shorthand once this spec issue gets updated.
