Draggable Droppable Issue

[th29805]

When attempting to drag a draggable item across a sortable list to a droppable element, the item being dropped gets lost. How can I maintain the item being dragged when it crosses over a sortable list?

Please review the issue at fiddle

Dragging the new task element down and to the right onto the drop here element works fine.

Dragging the new task element up over the sortable list and to the drop here element returns en invalid drop element.
