Thanks for taking the time to test it, we really appreciate it!  We just tried the reproduction on 14 beta 8 and it made it to 125 iterations (instead of 80), at which point it was unable to activate the camera.  After one refresh it was still unable to start the camera stream (just showed mic active).  After a second refresh, it started working again (which is improvement over iOS 13 which would never recover in the same tab).

We have been seeing increased rates of these dead streams in iOS 13.6/13.7 as we roll out more iPads, and are narrowing down a way to reproduce the issue quickly.  We will try to pin it down in such a way that we can reproduce it in a few seconds, and will attach the reproduction here when we have it.  Until then, any insight you have as to why the tab is permanently broken and what we can do to avoid this scenario would be much appreciated
