Implicit Root Scroller

Allows viewport-filling scrollers (iframes, divs) to perform document-level scrolling actions. I.e. show/hide URL bar, overscroll glow, rotation anchoring, etc.

Comments

This feature generalizes the special behaviors (typically on mobile) given today only to the documentElement to a other scrollers on the page. For example, show/hide URL bar on scroll. This allows authors to use non-document scrollers to host content and logically separate their application views in the DOM rather than moving everything into the documentElement.
