Buggy startup notification for WhisperBack
GNOME Shell does not detect when WhisperBack has finished starting: the spinner in the task bar keeps spinning (and once #19920 (closed) is fixed, I suppose the spinner on the desktop will do the same). Reproduced on 5.22 and 6.0~rc1.
This looks very much like #18330 (closed), which @boyska fixed with !457 (merged).
My hunch is that the fix for #19997 (closed) included in !1290 (merged) broke this by letting sudo drop the environment variable we need for this functionality.
