And why is that a problem?  Emacs displays partially visible lines at
end of window in many cases; as long as the list of completion
candidates is long enough, you cannot see all of them anyway.

Or maybe you have a specific recipe in mind where this works
incorrectly, in which case please show that recipe.

Thanks.
