   3     This test ensures the content overflow traversal correctness of spatial navigation:
   4     if an element if clipped overflow in a scrollable container (e.g. <div>),
   5     scroll-in-direction should happen in the container box, not on the outer view.
   6
   7     * Pre-conditions:
   8     1) DRT support for spatial navigation enable/disable.
   9
  10     * Navigation steps:
  11     1) Loads this page, focus goes to "start" automatically.
  12     2) Try to move focus down to the visible focusable element in
  13        scrollable div.
  14
  15     * Expected results: There should have to a scroll action in the container
  16     (div) as an attempt to make the clipped overflow node visible and accessible
  17     via spatial navigation. -->
