This bug will use the browsing context to notify content tab to mute/unmute media, instead of using MessageManager. We would use the top level canonical browsing context to
set the media mute property for the top level window and propagate it to other top level windows in other processes.
If we don't do so, we're not able to mute/unmute media in the different process when we we enable Fission, because the current way we use can only notify one process and would cause the media on other process can't be muted/unmuted.

We were incorrectly not performing an EnsureSubscribed for the origin
process which a BrowsingContext came from. Normally this would mean that
the BrowsingContext could die in the parent process before the
WindowGlobalParent listener arrived, but that didn't generally happen
due to the low likelihood of a CC occuring between the two messages.
It's likely that this crash was caused by people on lower-end hardware
triggering a print. This would be a longer-running operation in the
content process between the first and second message than usual. On
systems with memory pressure, there would be a higher chance of a CC
occuring between the messages, which would then cause this crash.
This patch correctly connects the origin ContentParent to the
BrowsingContextGroup, which will prevent the CC from destroying our
objects.
In the future, it may be desirable to ensure that this doesn't happen
more reliably by using a ContentParent-local table for looking up
BrowsingContext IDs sent over IPC. This would prevent our current
dependency on the weak pointer behaviour of the current global ID cache.
Unfortunately, this patch adds no tests, and I'm not aware of a good way
to test this edge case to confirm it has been fixed. I believe that this
patch should fix the issue I mention, however.

the cached mWindowProxy value doesn't have the chance to go away, but

itself to be cleared when it is destroyed, which caused the Remote
