Scroll functionality during drag and drop

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Put a dynatree with in an internal scrollable panel
2. Enable drag and drop
3. Drag an item outside the current view port
[apparent in example pages as well:  
http://wwwendt.de/tech/dynatree/doc/sample-dnd2.html#]

It seems like auto scroll functionality is broken - maybe an artifact of change 
in jqueryui/draggable? Maybe changes in more recent browsers?
In the example page, whenever the tree is contained within a view with 
scrollbars, you see the scroll bar shrink in size when dragging outside the 
viewport but no actual scroll happens (same behavior in both Chrome and IE10).

What is the expected output? What do you see instead?
Expect to see the tree scrolls so one can drag an item from one branch into 
another (non-visible) one at the time when drag starts.

What version of the dynatree and jQuery are you using?
1.2.4, 1.2.5

On what operating system and browser?
Windows 7, Browsers: IE10, Chrome

What DOCTYPE declaration are you using?

Please provide any additional information below.

Thanks for accepting this so fast, it would be great if a workaround/patch/fix 
for this could soon be published as the behavior here highly impacts our 
application using dynatree.

Thanks!

Indeed!

Adding 'position: relative' explicitly on the container works like a charm.

Thanks!
