So the frame will resize as result dragging by mouse, but the
mini-window will not be visible?

If that is the effect, then I'm okay with installing this on emacs-27,
but I wonder whether we could do better on master, so as to ensure
that at least one screen line of the mini-window is still visible?

Btw, is this issue new in Emacs 27, or did it exist before?

Thanks.
