Run it in the right step of the rendering loop as per spec. Keep the interruptible layout behavior by detecting whether we have any frame with content-visibility: auto / ResizeObserver / etc around. Also make the IntersectionObserver phase not unconditional, make it conditional on needing layout or having scrolled. I want to look a bit whether we can avoid flushing the whole browsing context tree, but that is pre-existing so not touching it as part of this work.
