Snappable elements are being returned as "snapped" when they should not be.  Here are the scenarios:

1) The draggable element is in between snappable elements

- Expected "snapped" elements = 0

- Actual "snapped" elements = 1

2) The draggable element is covering all or part of 1 snappable element

- Expected "snapped" elements = 1

- Actual "snapped" elements = 2
