When pinning a tab in which audio is playing, the mute icon overlay doesn't copy over to the pinned tab.
If the audio source in that pinned tab is stopped and restarted the mute icon does correctly appear.
If that pinned tab with active audio is unpinned the mute icon correctly move to the unpinned tab.
When pinning or unpinning a tab in which audio is playing the mute icon tab overlay should move with the tab to and from the pinned/unpinned state.
