What to do with threshold values other than 1 when trackVisibility is requested?

It's unclear what the behavior of IntersectionObserverEntry.isVisible should be if a threshold other than 1 is specified. Probably, we should require threshold=1 when trackVisibility=true, just as we also require that delay >= 100.
