  <!--
    This test ensures the optimization done in searching logic to find best candidate focusable node with minimum iterations.

    * Pre-conditions:
    1) TestRunner support for SNav enable/disable.

    * Navigation steps:
    1) Loads this page, focus goes to "2".
    2) lastSpatialNavigationCandidateCount() returns the number of nodes actually considered to determine best candidate focusable node,
       along the most recent navigation direction.
