Bug 260787

At safari 17, I encounter a problem:

When I capture video-stream from local camera, and set it to video's srcObject

The video play normally

Then I set srcObject to null and then set stream back

The video will not play.

----------------------------------------------

You can reproduce it at webrtc sample website.

1. Open : https://webrtc.github.io/samples/src/content/getusermedia/gum/
2. Click open camera button
3. Open dev-tools
4. Run code: const video = document.querySelector('video')
5. Run code: video.srcObject = null
6. Run code: video.srcObject = stream

Finally, The video will not play even if you call video.play(). But it is fine at safari older version(such as safari 16)

Thanks.
