Keyboard reordering doesn't show error message when trying to move a portlet above a locked portlet

Steps to reproduce:

1) Open the uPortal example from the daily build site:
http://build.fluidproject.org/fluid/sample-code/reorderer/portal/portal.html

2) Press the tab key until the one of the portlets has focus

3) Using the keyboard navigate to a movable portlet and attempt to move it above the locked portlet.

Notice that no error message is presented and the portlet wraps to the bottom of the column
