That is a shame. Pulled out an old macos virtual machine + an old Gimp 2.10
FWIW - see https://i.imgur.com/AdWRTWt.mp4 about 30 second demo
note no key press involved just the radio button.
So it could be the macOS or the version of Gimp or something else. Not many Mac users here, I use linux and only fire up that VM for problems such as yours.
If it is Gimp 2.10.22 you can report it as a bug https://gitlab.gnome.org/GNOME/gimp/-/issues
