If above the scroll limit, scroll to limit.

This case happens when you are scrolled to the end of the list and
you do an action that causes the view to shrink but not enough for
the scroll arrows to be detached such as remove a team or unexpand
an application. Before it would keep you where you were showing an
extra grey area, now it scrolls you back to the new scroll limit.
