<body>
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>
<br />
<div id="el" tabindex="-1">I will be focused automatically.</div>
<script>
window.addEventListener('load', () => {
el.focus();
});
async_test(function(t) {
el.addEventListener("focus", t.step_func(function() {
assert_equals(getComputedStyle(el).outlineColor, "rgb(0, 128, 0)", `outlineColor for ${el.tagName}#${el.id} should be green`);
assert_not_equals(getComputedStyle(el).backgroundColor, "rgb(255, 0, 0)", `backgroundColor for ${el.tagName}#${el.id} should NOT be red`);
t.done();
}));
