This test checks that any element focused via an <code>autofocus</code> attribute will have <code>:focus-visible</code> matching enabled.

<ul id="instructions">
|
|
<li>If the button that says "I will be focused automatically" has a red background, then the test result is FAILURE. If it has a green outline, then the test result is SUCCESS.</li>

</ul>

<br />
|

<button id="button" autofocus tabindex="-1">I will be focused automatically.</button>
