bug#62355: 30.0.50; C-g doesn't always quit minibuffer on first press

Hi,

For a while I've been having trouble C-g isn't quitting the minibuffer
after the first press.

When I start Emacs freshly I can press M-x, that triggers the
minibuffer, and pressing C-g quits the minibuffer again.

But after a short while of use this behaviour changes. Pressing M-x
still triggers the minibuffer, but pressing C-g prints "[Quit]" while it
keeps the minibuffer active. Only after pressing C-g a second time the
minibuffer is actually quit.

I was able to reproduce in "emacs -Q", but I haven't so far been able to
reproduce with "emacs -Q -nw", although I'm not sure it's related to any
of that.

Below is the output of "C-h l" (view-lossage) reproducing the issue:

 C-x b	 ;; switch-to-buffer
 C-g	 ;; abort-minibuffers
 M-x	 ;; execute-extended-command
 C-g C-g ;; abort-minibuffers
 C-h l	 ;; view-lossage

You can see the first time I press C-g once to abort-minibuffers. The
second time I have to C-g twice.

This time it happened right after a fresh start of "emacs -Q", but
sometimes I have to do a lot more actions before the double C-g is
needed.
