Webkit and jQuery draggable jumping

I draw a image to indicate the offset after rotate on different browsers as @David Wick’s answer.

Here’s the code to fix if you don’t want patch or modify jquery.ui.draggable.js

$(document).ready(function () {
    var recoupLeft, recoupTop;
    $('#box').draggable({
        start: function (event, ui) {
            var left = parseInt($(this).css('left'),10);
            left = isNaN(left) ? 0 : left;
            var top = parseInt($(this).css('top'),10);
            top = isNaN(top) ? 0 : top;
            recoupLeft = left - ui.position.left;
            recoupTop = top - ui.position.top;
        },
        drag: function (event, ui) {
            ui.position.left += recoupLeft;
            ui.position.top += recoupTop;
        }
    });
});
