| This test checks that programmatically focusing an element after a click does not cause <code>:focus-visible</code> matching to trigger. |
| <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 button below that says "Click me."</li> |
| <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> |
| </ol> |
| <br /> |
| <button id="button">Click me.</button> |
| <div id="el" tabindex="-1">I will be focused programmatically.</div> |
| <script> |
| button.addEventListener("click", () => { |
| el.focus(); |
