Drop-down menus cannot be opened in Firefox add-ons in Wayland session

[Kamil Rogozinski]

Drop-down menus in add-ons such as Bitwarden and Joplin Notes Web Clipper cannot be opened/expanded in Firefox 92.0+build3-0ubuntu0.21.04.1 under Wayland with AMD graphics. This issue is not present in an Xorg session.

Observed behaviour:
Clicking on the displayed menu item or down-arrow does not respond at all and does not reveal menu options.

Expected behaviour:
Drop-down menu opens and shows all menu options.

Workaround:
Click on menu item and use keyboard arrow keys to choose desired option

Thank you for your bug report, it seems the same issue than https://github.com/swaywm/sway/issues/6426 which seems could be fixed with https://gitlab.gnome.org/GNOME/gtk/-/merge_requests/3941

upstream comment also state 'Firefox 93 will fix that for old Gtk versions.'
