If you are on iOS Safari (maybe it does this on Android too, I don’t have an Android phone to check) have you:

* Looked at the top-right corner of that popup.

* Then, scan upwards from that corner, maybe 1cm above it

That’s where the x to close it is, for me. I’m not sure if it is screen specific or what, if it is a bug, etc. It doesn’t seem like a UI anyone would build intentionally but then, who knows?
