IntersectionObserver V2

Augment IntersectionObserver to report information about occlusion and visual effects. Currently, IntersectionObserver does not consider whether a target element has been painted over (“occluded”) by other content or whether any visual effects have been applied which may alter or obscure the element’s display. This change adds a boolean field to IntersectionObserverNotification, indicating whether the UA can guarantee that the target will be displayed unoccluded and without visual effects.
