The most current version of Drupal core appears to have upgraded the core version jQuery UI, and thus Sortable has been upgraded to 1.12. This version of Sortable is known to have performance issues, especially when coupled with lists containing a large amount of items.

To rectify this, I've leveraged a solution found here: https://stackoverflow.com/questions/20398400/jquery-ui-sortable-call-is-... and implemented it into the entityreference_dragdrop JS code. This code essentially prevents all the loading on the page load, instead opting to only load the drag/drop functionality when hovering the mouse on each individual item.
