Title: Fixed a bug and made two UX improvements.

BUG: Sortable helper was being counted as a sibling item in some situations.
UX FIX #1: Preventing accidental dragging of an item to the left.
UX FIX #2: Allowing items that have been dragged up a list to be dragged back down without skipping to the bottom.
