Thanks. I just noticed I haven't offer additional information. I'm on Emacs 28.
Info generated by report-emacs-bug is attached at the bottom.
The issue happens by chance. You have to be lucky (or unlucky) enough to
trigger it. Maybe you could close and reopen Emacs, and try it several more
times? I can't reproduce every time using the same recipe, but I'm lucky when
recording that gif.
I've asked in a forum if any company user has encountered the same problem
(
https://emacs-china.org/t/buffer/18062, in Chinese). Some said they've never
seen this, some have.

I tried the recipe (in Emacs 27.1), but I was unable to reproduce it.
