All right :),

As you can see there is a bit of code in the git core that I think
should really be examined and cleaned up or commented.

//Why do we do this?
    var offsets = element.positionedOffset(),
     top = element._originalTop -,
     left = element._originalLeft - offsets.left;

//Why does this work with this in????
    var isAuto = /^(auto|)$/;
    if (!isAuto.test( top += element._originalTop;
    if (!isAuto.test( left +=

//Without it unit some dom_tests (unit tests) fail.

Any ideas or insight would be great.
