Thank you very much. Despite still using GNU Emacs daily, I currently
don't follow the development version so I can't test the changes, but I
really appreciate your getting back to this after so many years.

It seems to me this was meant to read
(defun .update-old-selected-window (frame)
(unless (eq .old-selected-window (old-selected-window))
(setq .old-selected-window (old-selected-window))))
