this might be considered a bug.

Steps:

(0) start GNU Emacs with -Q.

(1) Define this: (defalias 'yes-or-no-p 'y-or-n-p)

(2) Then, in dired, type ~ to flag backup files. Then, type x to
delete them. Dired will prompt you with “Delete D [251 files] (y or
n)” with a list of files to be deleted on the top pane.

(3) When you have more files to fit in a window, part of the list is
not visible, and there's no way to view them. You can't page with
<M-next> or <M-prior>, can't use mouse to drag the scrollbar, scroll
wheel just produce beeps. Can't switch cursor focus.

thanks to Eli Zaretskii, Drew Adam for helping track down the cause.
