Can't use keyboard reordering to move a nested reorderer to the right column
Steps to reproduce:
1) Open the uPortal example from the daily build site:
2) Tab till one of the portlets has focus.
3) using the arrow keys put focus on the "image lightbox" portlet
4) press ctrl+(right arrow). Notice that the portlet doesn't move to the right column
Note if you use the mouse to put the "image lightbox" portlet in the right column, you can use the keyboard to move it back to the left column
