(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.

This fixes a bug that sometimes boosted statuses being hidden on scrolling.
Previously, we've attached IntersectionObserver twice for boosted statuses:
wrapper Status and wrapped Status. This will call intersection handler twice,
so this may results race condition...probably.
mergeDeep also merges columns, but it should be replaced simply.
So in the new function, first apply mergeDeep except columns, and set default columns if columns unset.
