If you expand the list and then use teh arrow keys to navigate into the dropdown the behavior is strange. First if you just use the down arrows, the first item selected is the one in the editbox. However, the next item is always the second item. It is as if ther internals think the first item is selected. Then if you repeatedly press the up arrow, eventually it transitions to the editbox and then when you try to press up again the list changes to only one item.
