[IntersectionObserver] Apply overflow clip to document.scrollingElement

If the explicit root element is the document's scrollingElement, we interpret
that to mean we should apply the root scroller's overflow clip (just as we
already do with the implicit root).

Hidden behind a flag for testing, and pending resolution of spec issues and
sending intent's.
