In the era of B2G, we wanted to hide the carets during scrolling, and PostScrollState was designed to avoid carets flicking during momentum scrolling. These days, we no longer hide carets during scrolling, so PostScrollState can be removed to make the code simpler and easier to maintain. MozReview-Commit-ID: Bf6ZgYVlt1q
