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>
<script>
promise_test(async function() {
await waitUntilStableAutofocusState();
assert_equals(document.activeElement, button, "Should have correct focused element");
assert_equals(getComputedStyle(button).outlineColor, "rgb(0, 128, 0)", `outlineColor for ${button.tagName}#${button.id} should be green`);
assert_not_equals(getComputedStyle(button).backgroundColor, "rgb(255, 0, 0)", `backgroundColor for ${button.tagName}#${button.id} should NOT be red`);
}, "Autofocus should match :focus-visible");
