This test checks that programmatically focusing an element after a click does not cause <code>:focus-visible</code> matching to trigger.
<ol id="instructions">
<li>If the user-agent does not claim to support the <code>:focus-visible</code> pseudo-class then SKIP this test.</li>
<li>Click the button below that says "Click me."</li>
<li>If the element that says "I will be focused programmatically." has a red outline, then the test result is FAILURE. If the element has a green background, then the test result is SUCCESS.</li>
</ol>
<br />
<button id="button">Click me.</button>
<div id="el" tabindex="-1">I will be focused programmatically.</div>
<script>
button.addEventListener("click", () => {
el.focus();
});
async_test(function(t) {
el.addEventListener("focus", t.step_func(function() {
assert_equals(getComputedStyle(el).backgroundColor, "rgb(0, 255, 0)", `backgroundColor for ${el.tagName}#${el.id} should be lime`);
assert_not_equals(getComputedStyle(el).outlineColor, "rgb(255, 0, 0)", `outlineColor for ${el.tagName}#${el.id} should NOT be red`);
t.done();
}));
