bug#53276: The blink-cursor-mode not work after startup on macOS

[Eason Huang <aqua0210@foxmail.com>]

Hi,

I found a problem when using Emacs 29 on macOS:

When Emacs is started at the first time, the blink-cursor-mode does
not work, and the focus needs to be switched to another
application, and then switching back again, it will work properly.

I tested with emacs -Q.
On other platforms (Linux, Windows) there is no such problem, It only
happened on macOS.



In GNU Emacs 29.0.50 (build 1, x86_64-apple-darwin19.6.0, NS appkit-1894.60 Version 10.15.7 (Build 19H1615))
