Scrolling not working on multiple item drag and drop for sorting on Windows

[sekaracrux]

Hi,

I am using this package for my site, in-order to sort items by drag and drop. When I select multiple items and drag for sorting, browsers like firefox, edge, chrome in windows machines are not auto-scrolling on moving the dragged items to top or bottom as like in the browsers used in linux/mac machines.

I also checked your demo(scrolling) on windows browsers where I experienced the same.
