This doesn't appear to be issue for: 
1. safari on macOS
2. chrome on macOS or android devices

This is probably the followon for https://bugs.webkit.org/show_bug.cgi?id=162366#c44

We have a use case, specifically to provide better webrtc experience:

For testing audio/video device, we allow user to see video preview for their selected device and at the same time we need to access the video stream for testing network connectivity.

Is there any reason why this limitation is only imposed to webkit on iOS?
 
This bug which only exists in safari iOS, prevents us from providing consistency experience across different browsers and different platforms.
