Navbar doesn't allow you to scroll all the way to bottom if more links exist than fit in screen window in sb-admin

If you have more links in your left nav than fit in your window, you can't scroll all the way down to see the bottom links. This is evident on http://startbootstrap.com/templates/sb-admin/ if you resize your browser so that it is smaller than all the nav links.
