Subject: 30.0.50; mode-line-format-right-align can make part of the modeline
 content disappear when eldoc is enabled
Date: Sun, 27 Aug 2023 13:18:56 -0300

Steps to reproduce:

+ Start Emacs with emacs -Q

+ Evaluate the following code:

    (setq-default 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
                    (vc-mode vc-mode) "  "
                    ;; Right align
                    mode-line-format-right-align
                    mode-line-modes mode-line-misc-info mode-line-end-spaces))

+ Type anything that triggers eldoc while in the minibuffer.  For instance:

    M-: ( c d

    [Wait for eldoc to appear]

+ Quit with C-g

Note that the right half of the modeline (which contains the major
mode) is no longer displayed.  It won't come back, not even with M-:
(force-mode-line-update) RET.  However, this only affects the current
buffer.
