The calendar buffer was configured to be sticky in a particular frame,
so that when emacs wanted to show that calendar buffer, it showed it in
the different frame.
I don't entirely understand how the stickiness happens -- configuration
of the emacs calendar is far beyond me.

Right. I believe that these need to be done "inside to out" i.e.,
(save-excursion
(save-window-excursion
(org-save-frame-excursion
....)))
in order that they unwind properly.
What I think is at least a bit odd is that I don't know of a case where
one would /not/ want the current frame focus to be restored when doing a
save-excursion. Admittedly it's unlikely (at least now) to get into a
state where you will change the frame focus, but whenever you /do/
change the frame focus, wouldn't you want it restored?
But this may simply expose my naiveté about emacs.
