  This test checks that <code>:focus-visible</code> always matches on elements with <code>contenteditable=true</code> set.
  <ol id="instructions">
    <li>If the user-agent does not claim to support the <code>:focus-visible</code> pseudo-class then SKIP this test.</li>
    <li><strong>Click</strong> the content editable span below to focus it.</li>
    <li>If the element has a red background, then the test result is FAILURE. If the element has a green outline, then the test result is SUCCESS.</li>
  </ol>
