See this example that illustrates the problem with IntersectionObserver in the above case.

I’ve also opened an issue with the W3C to consider this case in the spec, so perhaps something will come of that.

One other thing that might be effected by this implementation is “rapidScroll”. With intersection observer, we no longer have scroll position, just if it is entering or leaving. I guess if you have fireOnRapidScroll set to true, the component will have no choice but to install a scroll listener. But perhaps it could have a more aggressive throttle on it. Thoughts?
