Wrong position when draggable element or it's parent has transformations

[Syndikaattori]

When element or it's parent has transforms, eg. rotate or scale, the element translates to wrong position when dragging using JQuery UI Draggable.

For example these examples fail (tested in Mac Chrome 10 and Safari 5):

$("#element_id").draggable();

$("#element_id").css("-webkit-transform","rotate(10deg)"); $("#element_id").css("-webkit-transform","scale(2,2)");

$("#element_id").parent().css("-webkit-transform","rotate(10deg)"); $("#element_id").parent().css("-webkit-transform","scale(2,2)");

The problematic part seems to be _generatePosition() function which returns top and left position of element, but ignores all transformations. This bug makes using UI Draggable almost impossible in many situations.
