  <meta name="assert" content="In this test, a filled red image has a padding belt painted red and a red border. This test checks that the associated overlay for an image must not leak outside the image's border box.">

  <!--

  "
   For replaced content, the associated overlay must cover
   at least the entire replaced object, and may extend
   outward to include the element's entire content box.
   The overlay may also include other other areas within
   the border-box of an element (...)
