There is no change when reverting it against Emacs 29 or master. I
apologize for not mentioning this before. There is a change, however,
when reverting against the commit's immediate parent; so, coincidentally
or otherwise, the commit does manifest the behavior I've demonstrated. I
cannot speak to the ramifications for the rest of the codebase (I
understand much has likely changed in the two years since that commit
was made).

That is certainly interesting, as I can affirm this behavior was not
present in any version of Emacs 28 I've tested (up to emacs-28.3-rc1).

It does, and I thank you much for turning me onto that, as it at least
provides a usable fix for now.
