Note that I am experiencing the same bug in Pop OS 22.04 where Firefox is installed as .deb package (from Pop OS's own apt repositories) and there is no snap.
Anyway, wslu is installed by gimp-help-* and gets the following associations:
* Mime file types: MimeType=x-scheme-handler/http;x-scheme-handler/https;x-scheme-handler/file
* www-browser, via /etc/alternatives/www-browser -> /usr/bin/wslview
I know it's not pure Ubuntu but exactly the same bug in my opinion.
