   3     This test ensures the correctness of a basic aspect of spatial navigation traversal
   4     routines: focusable elements in scrollable containers (e.g. <div>) should be
   5     accessible, including offscreen content.
   6
   7     * Pre-conditions:
   8     1) DRT support for spatial navivation enable/disable.
   9
  10     * Navigation steps:
  11     1) Loads this page, focus goes to "start" automatically.
  12     2) Move focus down to the visible focusable element in
  13        scrollable div.
  14     3) Traverse the page through other focusable elements down the page.
  15        and then back up.
  16
  17     * Expected results: All focusable element in scrollable content, including
  18     offscreen ones, should be accessible via spatial navigation. -->
