Comment:
Mostly to make it work the same as with the firefox package which comes with firefox-wayland. I think we should either add thunderbird-wayland or remove firefox-wayland to make them behave the same.

Adding thunderbird-wayland is probably better for integration with firejail which comes with separate profiles for firefox-wayland / thunderbird-wayland. OTOH those profiles currently only include the normal ff / tb profile.
