<!--
  This test ensures the correctness of a basic aspect of spatial navigation's
  search for candidates to focus: an iframe element without any focusable content
  should be ignored.

  * Pre-conditions:
  1) Run chromium with --enable-spatial-navigation.

  * Navigation steps:
  1) Loads this page, focus goes to "start" automatically.
  2) Focus moves from "start" to "end" and return back.
