Reproduction steps:
1) Startup DXP 7.1 SP1 and login as admin
2) Open 'Menu' Side Bar on the left and go to Build › Navigation Menus
3) Create a Menu
4) Hit Edit › Add ('') button › Create 10 submenu items

Expected behavior:
Autoscrolling works up- and downwards.

Current behavior:
When reordering the submenu items, the window scrolls up during the event of drag & drop in the list. However, automatic scrolling down stops when trying to place an item from the top to the bottom of the list (see my screenshot).

Reproduced on:
