      Description

      The example below demonstrates.

      Control: Slowly drag between 1 and 2 and release at various points – when the drag is released, we snap to the closest item.

      Issue 1: Slowly drag between 0 and 1 and release at various points – it is very difficult to get it to snap to 0.

      Issue 2: Slowly drag between 2 and 3 and release at various points – it is heavily weighted towards 3 (it is hard to go from 3 to 2).
