WebRTC stop local tracks not disabling webcam after using replaceTrack

问题

I try to stop the browser webcam permissions indicator by using track.stop() like this:

myLocalStream.getTracks().forEach(track => {
    track.stop();
});

In most cases this works fine. But if during the session I have switched between different cameras by using replaceTrack() it will not work. The browser still shows a running webcam. The code for switching between tracks looks like this:

pc.getSenders().map(sender => {
    sender.replaceTrack(myLocalStream.getTracks().find(t => t.kind == sender.track.kind), myLocalStream)
});

It looks like after replacing the tracks, the browser has still some references to running tracks, that I don't know how to stop. Any suggestions?
