Public bug reported:

Image to illustrate the problem is attached. All firefox windows on
Wayland have a weird black protrusion from the top-left and top-right
corners where yaru has curved the window corners, but something from
Firefox appears to not be being clipped by the theme. I need to double
check whether this appears on X11, but for now consider it Wayland only
until I report back, although oSoMoN has checked their system and they
don't see the behaviour (on X11).

EDIT: I have now checked X11 on my system and I see the same behaviour
as described above, so this is affecting BOTH Wayland AND X11 for me.
