Then tell me, what happens when the menu is scrolled?  Since you've truncated
the menu height, you can no longer see the entire menu after it has been
scrolled.  In addition, in some cases, you might make the menu so small that
no items are visible.  I'd call that a bug.  The MDEF must work this way
or it could not ensure that the entire menu is visible and the desired item
is under the cursor.
