This only seems to happen in firefox (chrome seems to think you're selecting text when the cursor reaches the bottom, so it does scroll).
Repro steps:
you can see this happen on your examples page
-Navigate to http://one-com.github.io/knockout-dragdrop/examples/ in firefox
-scroll the page so a drag/drop area is half visible/half below the view area
-drag an item to the bottom of the view
Expected: page scrolls with dragging element still held
