Fallback cursor theme is ugly on Wayland
(initially filed against the firefox snap: https://bugzilla.mozilla.org/1709574)
I'm using the firefox snap on Ubuntu 21.04 in a Wayland session, and my desktop is configured to use a custom cursor theme (Oxy-blue) which isn't available in the
gtk-common-themes provider snap.
The mouse cursor theme in use is a very ugly one, where hovering over a hyperlink doesn't even display a hand with a raised index finger.
As my custom cursor theme isn't present in
gtk-common-themes, firefox should fall back to using the default DMZ-White theme (per gtk-common-themes!26 (merged)), as it does in an X11 session.
