1. Enable temp-buffer-browse-mode
2. (cl-loop repeat 2 do (with-output-to-temp-buffer "*test*" (princ "ok")))
3. Check pre-command-hook
#:clear-transient-map will be there forever.
The issue is caused by two identical calls of set-transient-map that
share the same keymap. so deactivation of the second call has an
side-effect on the first call.
Stefan, is the following the right fix?
Thanks,
Leo
