     31  This test checks that programmatically focusing an element after a click does not cause <code>:focus-visible</code> matching to trigger.
     32  <ol id="instructions">
     33    <li>If the user-agent does not claim to support the <code>:focus-visible</code> pseudo-class then SKIP this test.</li>
     34    <li>Click the button below that says "Click me."</li>
     35    <li>If the element that says "I will be focused programmatically." has a red outline, then the test result is FAILURE. If the element has a green background, then the test result is SUCCESS.</li>
