What I see here is that the frame where *scratch* is shown becomes the
selected frame, but input focus stays in the minibuffer frame, so if I
type the replacement string (without any refocusing), the command
accepts the replacement and starts replacing after I type RET.

YMMV, depending on your WM, I think.

The Subject says "Emacs 29.1", but this report is from Emacs 28.1.  So
which one is the version where you see the problem?
