I tested it on iOS 16.4, the issue is still present.

This is what happens:

### Safari Mode

1) Open Safari.
1.1) Navigate to https://safari-15-webrtc-issues.netlify.app
1.2) Switch to another app
1.3) Switch back to Safari
1.4) The video track receives events 'muted' and 'unmuted'. The audio track receives no events.
1.5) The app continues to work as expected.


### Homescreen standalone app

2) Open Safari, navigate to https://safari-15-webrtc-issues.netlify.app, Add to Homescreen to install the app on the iPhone
2.1) Open the app from the homescreen
2.2) Switch to another app
2.3) Switch back to the app
2.4) Both video and audio tracks receive event 'ended'. track.readyState is also 'ended'. 
2.5) The app does not work anymore. The stream is not usable and GUM have to be called again. The user have to allow usage of the webcam and the mic, AGAIN.


Is this the expected behaviour of the apps installed to the homescreen?

To me it seems like a BUG. Just switching to another app should not KILL the audio and video streams.
