Don't attach IntersectionObserver for wrapped statuses (#3883)
Don't attach IntersectionObserver for wrapped statuses (#3883)

(This patch has been merged as bugfix and reverted, but still valuable as
improvement)

Previously, we've attached IntersectionObserver twice for boosted statuses:
wrapper Status and wrapped Status. but wrapped Status don't need to manage
intersection and visibility by itself, because it's a part of wrapper Status.
