Steps to reproduce

NOTE: This is bug report for desktop flatpak Thunderbird! I'm posting it here because there's no repo for it on Github and I can't be arsed to file it on Bugzilla.

1. Burger menu - Tools - Export. Export your profile to .zip
2. Burger menu - Tools - Import - from file - Backed-Up profile - (choose your file)

Expected behavior

File is chosen and import is started.

Actual behavior

You are back in the same choice menu you were before and choosing the file again doesn't do anything.
