Currently, cua-mode has a bug i.e. when `(setq
cua-prefix-override-inhibit-delay nil)`, cut and copy do not work.

Also we have to`(setq cua-prefix-override-inhibit-delay nil)`,
otherwise cua-mode will not be able to support fast copy/cut & paste.

P.s. This patch based on the mirror repo
https://github.com/emacs-mirror/emacs
and Tested in Emacs 29.3.
