Title: Undesired clone sizing behavior for dragged items without fixed height 

When the list items do not have a fixed height the dragging clone has a fixed bottom location, making it resize as you drag around.

This simply copies the current height of the list item onto the clone when it gets created, effectively side-stepping the problem. No changes are made to the original item, so they can be resized as necessary after the drag.

Note: this will fail if the original item is resized while dragging is happening, but that is a much more complicated edge case that should probably be handled differently anyway.
