(This bug report unfortunately got no response at the time.)

I see that there's been some changes done to that function with regards
to how it selects windows before running FUNCTION, but I'm not sure
whether this fixes the problem or not, since there's no recipe to
reproduce the bug here.

Are you still seeing this problem in more recent versions of Emacs?  If
so, can you provide a step-by-step recipe to reproduce it, starting from
"emacs -Q"?
