Fix for RT-25049: SplitMenuButton have gap.

As near as I can tell, they have a gap going back a long way. In fact, the gap is still there with Region caching disabled (in fact with region caching turned on, you don't get this gap at all, so I think this error came from some time in the past). The MenuButtonSkinBase layout was incorrect, along with the CSS.
