The issue occurs when capturing "Your Entire Screen", "Application Window" or "Chromium Tab", not just "Chromium Tab". The video track simply abruptly goes mute in 4 seconds at Chromium 85.0.4173.0, where `inactive` event is still defined that event is fired. The `MediaStreamTrack` appears to be tied to some user activation scheme or algorithm, though per the specification should not be. Whether user action occurs or not `mute` event is eventually fired for no clear reason.
