Details

From 16bd2ac6-f021-49bd-9c7a-43e200221010 it seems that "FreeAudioSession" is dispatched to the main thread and may destruct the AgileReference to some COM object, resulting in some AudiosrvTsUnregisterAudioProtocolNotification call that seems to do some potentially long lasting RPC.

There has been some effort in bug 1755700 to simplify the ownership here, not sure if that qualifies as a regression, though.
