Title: Sortable: return to original position not last possible position. Fixed ...

This is the "#9099 - Sortable: Items in connected list revert to last list interacted with rather than their starting point" issue from bug tracker.

Fixed the issue for future releases by making sure that the item returns to the original position when dropped outside any sorted list. Previously it was dropped to the last possible position.
