2) Add the app to the home screen
3) Launch the app from the home screen
4) Browse around in the app

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.
