| This test checks that any element focused programmatically on page load will have <code>:focus-visible</code> matching enabled. |
| <ul id="instructions"> |
| <li>If the element that says "I will be focused automatically" has a red background, then the test result is FAILURE. If the element has a green outline, then the test result is SUCCESS.</li> |
| </ul> |

| <div id="el" tabindex="-1">I will be focused automatically.</el> |

| window.addEventListener('load', () => { |
| el.focus(); |
| }); |

| el.addEventListener("focus", t.step_func(function() { |
| assert_equals(getComputedStyle(el).outlineColor, "rgb(0, 100, 0)"); |
| t.done(); |
