Status changed to 'Confirmed' because the bug affects multiple users.

Package details could be wrong !

I asked on discord (ubuntu testing week rooms) & someone tested on a ubuntu jammy system and reported NO ISSUE.

I zsync'd the Xubuntu DAILY (20220402) and had no issues there either, so possibly lubuntu issue only.

Yes, xdg-open detects the desktop environment and behaves differently depending on it. This is a duplicate of bug #1973470.
