When some zimit2 ZIMs are re-opened in PWA on Android, the content of the iframe cannot be interacted with

I'm seeing this on some small test ZIMs, where I suspect the landing page gets cached. In any case, the iframe is not properly enabled for touch input. I suspect the scrollbox div is in the foreground and hasn't properly been reset.

Needs debugging as it's very annoying.

This only affects Android, not the PWA in desktop browsers. It must be a race condition due to Android being much slower.
