Dropdown menus being chopped off within .tab-content

Created by: jplock

I'm using a dropdown menu within a .tabbable nav and if the dropdown menu extends beyond the bottom of the <div class="tab-content">, the menu gets chopped off. I noticed between 2.0.0 and 2.0.1, a "overflow: hidden" was added to ".tab-content" and if I toggle that off in firebug, the issue is resolved.
