CSS `overscroll-behavior` allows developers to decide the browser's behavior once a scroller has reached its full extent. The unused delta can be propagated to the parent causing scroll chaining, create a glow/bounce effect without chaining, or just get consumed silently. This would be a standardization of "-ms-scroll-chaining" with some modification.
