Description Christoph 2020-04-27 00:30:22 PDT 
Steps to reproduce:

- hold iPhone in portrait mode
- open a PWA, e.g. https://sudoku.jull.dev/
- save it to Home Screen
- open newly saved PWA from home screen
- open another app, e.g. Safari - change display orientation to landscape, then back to portrait
- switch back to the PWA

After those steps, the PWA is frozen and can't be used anymore. It needs to be closed via the task switcher. This happens on EVERY PWA I have tested.

Could you please take a sysdiagnose while in the state, and attach it to a new bug report via feedbackassistant.apple.com? Please post the feedback ID here for reference.

I've just sent the feedback, feedback ID: FB7687121

Why doing so, I noticed an interesting fact: when I have "AssistiveTouch" active during the steps to reproduce the bug, the bug does NOT happen. Without AssistiveTouch it still happens though.
