There's a glitch in Proton Drive. What I infer is a confirmation prompt, shows only the merest portion of the upper segment of a tooltip balloon shape, but NO text, when I try to delete files.

Tapping on the poorly rendered element results in the file being deleted. Tapping elsewhere on the screen does not delete the file.

This happens in the iPadOS Proton Drive native app. Using an Apple external tablet keyboard attached, in case that matters.
