My understanding of the scenario in this report was that the value of
selected_frame didn't have time to become updated before redisplay
kicked in. If you think the problem is elsewhere, I'm okay with
leaving this crash in emacs-27 until we understand the cause of that
and fix it elsewhere. I just hope you will have the solution quickly
enough to not release Emacs 27 with this crash.
Thanks.
