FF149 fixes some bugs around capturing streams and whether audio volume, which are described in https://bugzilla.mozilla.org/show_bug.cgi?id=2010427#c8

Specifically mozCapureStream() is supposted to capture a raw stream, unaffected by the underlying media element volume, while MediaElementAudioSourceNode is supposed to respect the setting of the raw stream. Now they do.

This is related to the updates in #43323

Related work for this can be tracked in #43215
