Whether this is a bug is then a matter of opinion and actually complicated[1]. You may need to convince Gnome maintainers about it or use another desktop environment.

This is either a regression of the snap package vs deb or ubuntu 20.04 vs ubuntu 18.04 (I am not able to differentiate between these two since both happened together).
