viewport moving while dragging

viewport moving while dragging


hey there,
i have another problem with the Draggable function. i have built a
little page with an large background image thats draggable vertically.
on that image is an absolute positioned box that is not draggable.
now, when i drag the big image out of the viewport, the box is
scrolling upwards, and doesnt come back when i stop dragging.
i made a little example piece to show you what i mean:

and a video if my description sucks:

Can anybody help me to solve this problem? :/
