The check in the patch is whether the buffer of the
minibuffer-selected-window is the current buffer. It's meant to fail
when you are about to start a recursive minibuffer.

The original code assumed that when you are about to activate a
minibuffer, the current buffer will become the (window-buffer
(minibuffer-selected-window)). This is not true if you are entering a
recursive minibuffer, hence the check.
It may or may not be the best patch, but I would say it's the safe one
if were to fix this in Emacs 29. I would also say the issue rare and
basically cosmetic.

New in Emacs 29.
