It appears that in landscape mode in web app, events are not fired for touches happened at the top ~10 pixels. This is presumably where the status bar would reside if it was visible. The issue is not reproducible in portrait mode, nor in a regular native app.


1. Visit https://ywh233.github.io/
2. Add the site to home screen
3. Open the site from the icon on home screen
4. Rotate phone to landscape
5. Tap `iOS unresponsive top area in landscape mode repro`
6. Try to tap `Tap here` a few times


The dialog should pop up every single time you tap the link


The dialog only pops up if you tap the lower part of the link. While in portrait mode, the link seems to be much more responsive.
