> Replace homebrew scrollbar in Files app with that of Blink.
> 
> When overlay scrollbar is enabled in Chrome, there is animation to shrink and fade out the scrollbar thumb when inactive. However, scroll bars that aren't composited will not be animated
> (see Issue 671644). It would make the scroll bar always thick and simply disappear without fading out after inactive.
> As a workaround, this change makes the 2 boxes have solid background and contain:paint so as to make sure the scrollers are composited.
