+  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.</div>
