In iOS 15.4b1 (tested on iPhone 11), using the captureStream() method to set the srcObject of the <video> element is not working, resulting in a black screen.

Minimum repro test: https://webrtc.github.io/samples/src/content/capture/video-video/
Expectation: the video on the left is streamed to the <video> on the right
Result: a black screen instead of the video stream
