Definition and Usage
The overscroll-behavior-y property is used to turn off scroll chaining or overscroll affordance on an element when you try to scroll past the scroll boundary in y-direction.
Scroll chaining is when overscrolling on an element leads to scroll behavior on the parent element. This is default behavior.
Overscroll affordance is a feedback to the user when trying to scroll beyond the scroll boundary. For example, a visual feedback together with a page refresh normally happens on mobile devices when tying to scroll beyond the top of a page.
