Test page

Showing an alert while in element fullscreen causes fullscreen to exit (this part is expected) but after that it is impossible to re-enter fullscreen. This reproduces in Safari on iOS 15.4 as well as Safari 15.4 on macOS. 

Steps to repro with the attached test case:
1) Tap the "Launch fullscreen" button
2) Once in fullscreen, tap the "Trigger alert" button.
3) Fullscreen will exit and an alert will be shown
4) Dismiss the alert
5) Tap the "Launch fullscreen" button to try to re-launch fullscreen.

Expected result: Back in fullscreen
Actual result: Nothing happens
