Vertical scroll if view port is less size than the folder bag size

Looks like the issue is fixed in dragula but I am using this module for my project. Is there any way to add same thing here. I tired to use one solution given in the bevacqua/dragula#327 but when I drop item the page scrolls down

@bevacqua Please provide some inputs so that I can start think of solution to fix that jumpy issue
