Description Virginia Farley 2021-10-13 16:22:20 PDT 
This behavior can be seen by navigating to https://virginiafarley.github.io/samples/src/blank-video/ and following the below steps:

1. On iOS 15.1 beta, open the link https://virginiafarley.github.io/samples/src/blank-video/ in Safari
2. Click the "Capture audio" button and allow microphone access when prompted
3. Click the "Capture canvas" button
4. Observe that video is not already playing (must press "Play Video" to play)

Expected behavior: Clicking "Capture canvas" will result in autoplay of video.  Video should be playing, not paused.

Able to reproduce with iOS 15.1 beta. Unable to reproduce with iOS 15.0. No repro when creating PWA out of this link.  Unable to reproduce when flip steps 2 and 3 - you can only reproduce bug by capturing audio first.

This should now be fixed in STP 139, iOS 15.3 Beta, and macOS 12.2 Beta.
