No more comments, so I'm now closing the bug as done.

[Message part 3 (message/rfc822, inline)]

When using multiple graphical frames, setting ido-max-window-height to 1
only works as expected on the initial frame. On all other frames,
supposing the minibuffer length is great enough, the beginning will be
occluded until user input is received.

This can be easily demonstrated by running the following code on a fresh
graphical Emacs, and then pressing C-x b to switch buffers:

(progn
  (ido-mode 1)
  (setq ido-max-window-height 1)
  (dotimes (i 100)
    (generate-new-buffer "foobar"))
  (make-frame))

The bug manifests on both Linux and macOS (vanilla builds). It was not
present on Emacs 28. I ran a git-bisect and the "first bad commit"
appears to be c0b9041ebde82907711cc00a7c307fe622fb541c.
