-// Wrapper for IntersectionObserver in order to make working with it
-// a bit easier. We also follow this performance advice:
-// "If you need to observe multiple elements, it is both possible and
-// advised to observe multiple elements using the same IntersectionObserver
-// instance by calling observe() multiple times."
