> I understand that this is an edge case currently (with the patched mutter) but I foresee this becoming a "problem" when in a year or two all other apps also have rounded bottom corners and Firefox is the odd one out, I think fixing this now is a good idea to prevent technical debt.

Getting bottom corners rounded on Wayland seems worth a separate bug.
