User-agent: Gnus/5.13 (Gnus v5.13) Emacs/27.0.50 (x86_64-pc-linux-gnu)

Try to eval in emacs -Q in *scratch*:

(progn (dired "/tmp") (dired-next-line 1)
       (split-window) (other-window 1)
       (dired "/tmp") (dired-next-line 2)
       (let ((w-c (current-window-configuration))
             (p-m (point-marker)))
         (view-emacs-todo) (delete-other-windows)
         (with-current-buffer (get-buffer "tmp")
           (revert-buffer))
         (set-window-configuration w-c)
         (goto-char p-m)))

Result:
- point in the selected Dired window moves to point-min
- point in the non-selected Dired window moves to point-max
