Sortable scroll issue with connected lists

Question

I have an issue with jQuery UI sortable plugin, for some reason, it fails to scroll correctly when used with connected overflowed, scrollable lists.

Please take a look at this JSBin demo

Now, the issue is when you try to drag list item from List 1 to List 2 (or the opposite) and drag it to the bottom edge (or top, if I am trying to drag it to top), the List 1 will scroll instead of List 2. I tried my luck with scroll, scrollSensitivity, scrollSpeed but had no luck with these options.

I appreciate any help with this problem. Thank you in advance!
