Lockbox auth screen locks up Firefox iOS UI

I can't repro, but this was reported twice now. After returning to Firefox iOS, the app won't receive any taps until the app is backgrounded and foregrounded again. One user confirmed they have a custom keyboard app installed.

STR: go to page with a login/password form, tap to give focus to form field, tap the keyboard accessory for Passwords, perform thumbprint auth on Lockbox auth screen that pops up, select a login/pw, upon return to the Firefox app it is locked up.

@garvankeeley can you be more specific? is this referring to Lockbox auth in an autofill context, or ??

Right, I'll update the description

I wonder if this is a bug with all third party password managers when showing the auth screen, in which case we can close this one here. I filed in both places until we get some idea of where the bug originates, seems more likely to be in Firefox iOS.
