bug#45913: 28.0.50; Cursor doesn't blink after `make-frame-on-display`

[Stefan Monnier]

Package: Emacs
Version: 28.0.50


If you do:

    emacs -Q -nw

followed by

    M-x make-frame-on-display RET :1 RET

The cursor doesn't blink in that new GUI frame, whereas if we do the
reverse (start `emacs -Q` followed by the creation of a tty frame),
the cursor does blink in the GUI frame.
