  This test checks that using keyboard combinations with [Ctrl], [Alt] or [Cmd]
  do not trigger <code>:focus-visible</code> matching.
  <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 the element below that says "Click me, then use a keyboard shortcut."</li>
    <li>Press a keyboard combination including [Ctrl], [Alt] or [Cmd], such as <code>Ctrl</code> + <code>y</code></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>
