This also resets IntersectionObserverWrapper on disconnect to avoid `unobserve()` calls
which has bug in Edge.

(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.

* Replace TextIconButton for SensitiveButton to IconButton

* line-height

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.

* Bring Toot button in line with counter

Both should use stringz I guess

* Use grapheme_length for character count
