  This test checks that <code>:focus-visible</code> is <em>not</em> triggered by mouse focus on <code>&lt;input&gt;</code> elements which do not take text input, even if <code>appearance: none</code> is used.
  <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>Click each element element below to focus it.</li>
    <li>If the element has a red outline, then the test result is FAILURE. If the element has a green background, then the test result is SUCCESS.</li>
