Open external app button events unreliable

I use an external torrent app LibreTorrent. When I click on magnet links, FF133 faithfully opens the external app handler. However when I tap the OK button FF very often ignores my tapping. I can hit several times with no effect. I can see a quick circle showing as I tap, so the tap is generating an event, but FF does not react to it. This happens in normal and private mode. Sometimes after a couple or perhaps a dozen or more taps, the OK event has an effect and the external app launches fine.

A very curiously I accidentally noticed that if I tap or swipe the text also showing on the dialog box before tapping OK, the first tap on OK always works! 100% reliable. Something is fishy with event handling.

Repro: FF133 + current LibreTorrent client, then tap of first magnet link at https://webtorrent.io/free-torrents

Update on workaround (FF Android 133.0.3):

When the "Open in app?" dialog shows, if you *first* tap once on the URL text shown, then on the "Open" button, the button works. I've done this about 10 times in a row.

You get *one* chance to do this -- if you tap Open first, and it doesn't work, you're stuck re-trying tapping, noting that alternating between URL text interaction and Open seems to resolve faster.

The external app in this case is LibreTorrent 3.5.2, but surely that app cannot cannot cause FF's "Open" button to ignore taps, right?
