Current behavior
If a page is scrolled vertically, and a user tries to drag a draggable Dialog modal, it quickly moves to the bottom and gets stuck there.

Expected behavior
The modal should follow the user's mouse.

Minimal reproduction of the problem with instructions

I've been encountering a similar issue all the way back in version 11.4.2 (Not LTS).
If the page is at the top of the screen, I can drag correctly. If I have scrolled down, vertical dragging seems disabled/huggs the bottom of the screen.

EDIT: From what it looks like, its looking like it doesn't take consideration of the scroll position of the page.
