(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

You say "currently", but not what Emacs version this was about.

I tried evaling the form above in Emacs 25.1 and Emacs 29, and it didn't
fail in either of those cases, but perhaps there's something missing in
the recipe?  Or has this gone away since whateve version you say this in?
