Audio capture needs to be reselected every screenshare despite visual indications

On the second screenshare, menus show that the app audio from last time is still being captured, but it doesn't actually capture until you toggle things.

Expected behaviour Either the audio capture setting should be remembered, or it should visually indicate that the audio capture setting has reset to None so the user knows to reselect the audio capture setting. Personally I'm fine with having to reselect.
