We plan to move the visibility tracking to IntersectionObserver based implementation (#5697). However, because IntersectionObserver only fires at a list of pre-specified thresholds, metrics like minVisiblePercentage and maxVisiblePercentage will not be available.

An approximate is achievable by specifying a fine grained list of thresholds, for example from 0 to 1 with step of 0.05. Is it something we should go for or we can stop supporting this anymore.
