Revert to wrong position with rotated elements

When using the revert-option on rotated elements (e.g. an image), the image is reverted to the wrong position.

Code: http://jsfiddle.net/VuNW6/

On the left both elements are not rotated: Everything works.

On the right one element is rotated: If you drag this item, it will revert to wrong position, every time you drag it.
