When dragging the center point of a range in a multi-slider, every effort should be made to preserve the size of the range. E.g. currently in a slider where the end points can't be dragged beyond the ends, if the user tries, the range will shrink to zero as the top is constrained but the bottom is moved, or vice-versa.
