If a horizontal RadSlider is set with ItemType=Tick or ItemType=Item, its decrease and increase handles are disabled and the MetroTouch/BlackMetroTouch skin is used, the ticks will not be positioned correctly. The effect depends on the value of the TrackPosition property:

   - If TrackPosition=TopLeft, all ticks will be misplaced.
   - If TrackPosition=BottomRight or TrackPosition=Center, the last tick will appear on a new line.
