Subject: 30.0.50; Modeline position not being updated while using
 mode-line-format-right-align
Date: Tue, 18 Jul 2023 18:15:27 +0200

mode-line-position does not get updated consistently when used in
combination with mode-line-format-right-align in mode-line-format.

Evaluate the following code in the *scratch* buffer, then C-n and C-p
and observe how the line counter on the mode line is not updated most
of the time:

(setq mode-line-format '("%e" mode-line-front-space
 (:propertize
  ("" mode-line-mule-info mode-line-client mode-line-modified
   mode-line-remote)
  display (min-width (5.0)))
 mode-line-frame-identification mode-line-buffer-identification "   "
 mode-line-position
 mode-line-format-right-align
 (vc-mode vc-mode) "  " mode-line-modes
 mode-line-misc-info mode-line-end-spaces))

Notice that mode-line-format-right-align was added just after
mode-line-position.

Hugo, can you please look into this?

Actually, I think I just fixed this.

No further comments, so I presume the problem is indeed solved, and
I'm closing this bug.
