The video is still processing, but the URL is https://www.youtube.com/watch?v=3Qcq3IHUbv4.

(In reply to Thomas Steiner from comment #1) > The video is still processing, but the URL is > https://www.youtube.com/watch?v=3Qcq3IHUbv4. Processing is done now. (Don't get confused by the flashing light next to the iPhone X's ear piece, it's a weird reflection of the recording phone's autofocus infrared light. The camera panning was to enable Face ID.)

Update: this happens in stand-alone Safari as well, the issue is _not_ limited to add to home screen launches, but happens universally.

It seems like conducting a search reliably triggers the issue, sometimes after one, sometimes after three or four letters.

I doubt this can be a WebKit bug. Also, this issue does not reproduce here.

FWIW, this is no longer happening on Beta 6 (Build 15E5216a), so I guess the bug can be closed for now.
