I I believe this is fixed in testing/unstable by 3.24.34-5 and 3.24.35,
can you confirm?

This seems like a change in sufficiently core code that I would want to
watch for regressions in testing/unstable for some time before considering
a backport.

I've added it to <https://wiki.debian.org/Gnome/BullseyeUpdates>.
