bug#53073: 29.0.50; Emacs daemon --with-pgtk does not show modus-vivendi cursor

[Protesilaos Stavrou]

Dear maintainers,

While using the pgtk build, any emacsclient frame that starts the daemon
fails to show the cursor on the current window when the active theme is
'modus-vivendi'.

Steps to reproduce:

* Include just the following in the 'init.el' file:

    (add-hook 'after-init-hook (lambda () (load-theme 'modus-vivendi)))

* Launch Emacs with:

    emacsclient -c -a ''

* Notice that the cursor is not visible in the scratch buffer.

* Type 'C-h o' (or 'M-x describe-symbol') and search for 'cursor'.

* In the resulting Help buffer, notice that the background attribute is
  "#ffffff" (white), which is correct.

* No white cursor is visible (see attached screenshot).
