   the page is being scrolled or the user is interacting with the
   track/thumb, and fades back out after a short idle delay.

   scrubber is a shortcut on top of the natural document scroll, not a
   replacement for it, so content remains reachable via keyboard and
   normal wheel/touch scrolling. */
