Correct. Having scrollTop/Left have subpixel precision without having
the same for scrollWidth/Height seems really inconsistent and
unfortunate though. I really do think that we need to have some way to
get the precise scrollable size, be that though changing
scorllWidth/Height or by adding a new getScrollableSize/Rect API.
