From https://drafts.csswg.org/css-overflow/#overflow-propagation: > UAs must apply the overflow-* values set on the root element to the viewport. > However, when the root element is an [HTML] html element (including XML syntax > for HTML) whose overflow value is visible (in both axes), and that element has > a body element as a child, user agents must instead apply the overflow-* > values of the first such child element to the viewport. The element from which > the value is propagated must then have a used overflow value of visible. This was out of sync with Document::IsScrollingElement, which implements the right thing.
