Code Reproduction

Using the two-finger swipe up gesture on iOS does not cause VoiceOver to speak the entire screen from the top when a website is running as a home screen app.

Steps to Reproduce:

1. Open attached Code Reproduction on an iOS device.
2. With VoiceOver enabled, use two fingers to swipe up on the web content. You should hear VoiceOver correctly speak the entire screen from the top.
2. Add the code reproduction to the home screen.
4. In the home screen app, use two fingers to swipe up. VoiceOver will not speak the entire screen from the top. You should just hear a "pop" noise.


Expected Behavior:

I would expect that VoiceOver reads the entire screen from the top when using the two-finger swipe up gesture.


Actual Behavior:

VoiceOver does not read the entire screen from the top.


Other Information:

- Using the two-finger swipe down gesture (read screen from selected item) works as expected.
- I can reproduce this on the iOS 14.6 developer beta.
- This reproduces in a WKWebView instance as well. Please let me know if you would like a reproduction with that as well.
