I don't think this will work reliably, e.g. even if your minibuffer only
has N lines of text, line wrapping different fonts used for different
scripts, plus overlays and text-properties applied to specific parts of
the minibuffer's content will make that computation fail to give the
desired result.

It might not even be possible anyway if the minibuffer's content uses up
more space than available in the frame.

Indeed, which is another problem with this option.

That sounds good.  It's not sufficient to fix the problem in
`icomplete-vertical` obviously, so `icomplete-vertical` would need to
be changed.  Maybe it could check the `window-end` to detect when the
minibuffer's content is larger than what fits and shorten
it accordingly?
