In a MultiColumnList, when the vertical scrollbar appears, it "steals" some of the list area (a sliver along the right side). As a result, the header widgets are now too wide to display in the list area. This causes the horizontal scrollbar to appear, even though the horiz scrollbar should not be required to display the list entries.
Perhaps the ideal fix would be this: The vert scrollbar is instead drawn outside of the list area, such that the list area doesn't get any smaller when the vert scrollbar is added.
Steps to reproduce: - Create a MultiColumnList - add 2 columns of width 0.4 and 0.6 - add list entries until the vertical scrollbar appears - note the horizontal scrollbar also appears, even though the listbox items do not require the horizontal scrollbar.
