bug#61319: 30.0.50; 'M-x select-frame-by-name' --with-pgtk does not switch focused frame

[Protesilaos Stavrou]

Dear maintainers,

When using Emacs PGTK, the command 'select-frame-by-name' does not
switch focus to the selected frame.  Instead, it selects the buffer on
the specified frame, but keeps the current frame in focus.

Steps to reproduce with 'emacs -Q':

1. In the scratch buffer, do 'M-x make-frame'
2. In one of the two frames, switch to another buffer, such as "*Messages*".
3. Do 'M-x select-frame-by-name' and select the other frame.

I attach a screenshot that shows the mismatch between the focused frame
and current window.  I disabled blink-cursor-mode to capture the cursor
in the screenshot.

I tried this on GNOME Wayland.

This does not happen when I compile Emacs WITHOUT --with-pgtk.

Please let me know if there is something else I could test or modify.

Thank you for your time.

All the best,
Protesilaos (or simply "Prot")
