Overlay scrollbars are too difficult to use when animations are disabled
Problem:
Grabbing an overlay scrollbar is unnecessarily difficult when animations are disabled. If a user overshoots a scrollbar when moving the cursor towards it, it collapses from the expanded state back into the compact state immediately. So it becomes an annoying task of trying to grab it when it's expanded.
Suggested solution:
An overlay scrollbar should stay expanded for a short duration once expanded so the user doesn't have to repeatedly expand it.
