use jQuery UI dargable

I use the dargable JQuery UI, encountered a problem. My browser is Google browser, the page is a scroll bar. I drag it. If the scroll bar is greater than zero, the position and the mouse position of the drag element can be offset. English is not very good, please forgive me           This is the wrong picture..               This is the right picture..
