The change in browser_net_view-source-debugger.js is needed because we now use WebIDL callbacks for MessageListener, and they add async creation stack frames.

KeyframeEffect and KeyframeEffectReadOnly constructors can run in the caller
compartment, which is okay because the current compartment is used in the
following places and all of them are safe:
1. GlobalObject::CallerType(), that is ultimately passed to
nsDocument::IsWebAnimationsEnabled in KeyframeEffectParamsFromUnion,
to decide whether to copy mIterationComposite/mComposite to
KeyframeEffectParams.
GlobalObject::CallerType() can now be different than the target window's one,
if the caller has the system principal and the target is web content, and
in that case nsDocument::IsWebAnimationsEnabled there always returns true
while Web Animations can be disabled on web content.
honoring the mIterationComposite/mComposite properties is OK, since it just
changes the animation behavior, and this is disabled by default until
remaining spec issues are resolved.
2. GlobalObject::Context(), that is ultimately passed to
KeyframeUtils::GetKeyframesFromObject and used while extracting information
from passed-in keyframe object, with iterable/iterator protocols.
Performing that operation in the caller side is okay, since the same thing
can be done on caller, and the operation doesn't perform any GCThing
allocation on the target window global.
KeyframeEffect and KeyframeEffectReadOnly constructors can run in the caller
compartment, which is okay because of the following reasons:
1. The target window global is used for most operation:
* KeyframeEffectReadOnly::ConstructKeyframeEffect uses the target window
global instead of current global.
* KeyframeEffectParamsFromUnion which receives `aGlobal.CallerType()`
In Xray case, Web Animations API can be disabled on web content
(currently disabled on beta/release by default), and in that case some API
won't work even it's triggered from WebExtensions, but it should be fine.
2. GetKeyframesFromObject is executed in the caller's compartment to access
the passed-in JSObject that is keyframe, with iterable/iterator protocols.
This operation doesn't perform any GCThing allocation on the target window
global.
I looked at the diff in the generated code, and the only change is that
SpeechRecognitionEvent's unlink impl goes from:
NS_IMPL_CYCLE_COLLECTION_UNLINK_BEGIN_INHERITED(SpeechRecognitionEvent, Event)
NS_IMPL_CYCLE_COLLECTION_UNLINK(mResults)
tmp->mInterpretation.setUndefined();
NS_IMPL_CYCLE_COLLECTION_UNLINK(mEmma)
NS_IMPL_CYCLE_COLLECTION_UNLINK_END
to:
NS_IMPL_CYCLE_COLLECTION_UNLINK_BEGIN_INHERITED(SpeechRecognitionEvent, Event)
NS_IMPL_CYCLE_COLLECTION_UNLINK(mResults)
NS_IMPL_CYCLE_COLLECTION_UNLINK(mEmma)
+ tmp->mInterpretation.setUndefined();
NS_IMPL_CYCLE_COLLECTION_UNLINK_END

These are cases that are implementing the "convert an exception to a Promise"
steps of the Web IDL spec. Typically the exception is thrown in the current
compartment; the Promise returned should simply match that. Otherwise we can
end up with a situation in which the promise doesn't actaully have access to
its rejection value, which will cause problems if someone uses then() on the
promise: the return value of the then() call will get a sanitized exception
instead of the real one.
We _could_ try to match the actual compartment of the exception, in theory.
But it's not clear why this would be preferable to using the current
compartment, even if there were cases in which the exception _doesn't_ match
the current compartment. Which there likely are not.

We currently don't generate a ::ToJSON() method for WebIDL types with record<K,V>
members. These types should be safe to convert to JSON, as long as type V itself
is. Per spec, type K is always a DOMString, USVString, or ByteString.
This patch was autogenerated by my decomponents.py
It covers almost every file with the extension js, jsm, html, py,
xhtml, or xul.
It removes blank lines after removed lines, when the removed lines are
preceded by either blank lines or the start of a new block. The "start
of a new block" is defined fairly hackily: either the line starts with
//, ends with */, ends with {, <
