It seems that the new code changed the logic.  Now
rmail-summary-window-size doesn't take effect.  As I didn't
customize rmail-redisplay-summary, its value is nil.  And
the new code handles rmail-summary-window-size only if its
value is non-nil.

    (and rmail-summary-buffer (buffer-name rmail-summary-buffer)
         rmail-redisplay-summary   ;; <--- !!!
         (setq window
               (display-buffer
                rmail-summary-buffer '(nil (reusable-frames . visible))))
         rmail-summary-window-size
         (setq size (- rmail-summary-window-size (window-height window)))
         (window--resizable-p window size)
         (window-resize window size))))
