Title: Draggable: parent storing

Having a draggable connected to some sortable lists and the draggable is moved into one of the sortables then into another one - and the sortable lists are close to each other without gap - the stored parent becomes the previous sortable and when moving out of the latter sortable causes the draggable stick inside the previous sortable.
