This test checks that <code>:focus-visible</code> matches after a keyboard event,
even if the event handler calls preventDefault() on the event.
<ul id="instructions">
<li>Click "Click here and press right arrow.".</li>
<li>Press the right arrow key.</li>
<li>If the element 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 />
<div id="target" tabindex="0">Click here and press right arrow.</div>
<script>
target.addEventListener("keydown", (e) => {
e.preventDefault();
});
target.addEventListener("keyup", (e) => {
e.preventDefault();
});
target.addEventListener("keypress", (e) => {
e.preventDefault();
});
async_test(function(t) {
target.addEventListener("focus", () => {
const arrow_right = "\ue014";
test_driver.send_keys(target, arrow_right);
});
target.addEventListener("keyup", t.step_func_done((e) => {
assert_equals(getComputedStyle(target).outlineColor, "rgb(0, 128, 0)", `outlineColor for ${target.tagName}#${target.id} should be green`);
assert_not_equals(getComputedStyle(target).backgroundColor, "rgb(255, 0, 0)", `backgroundColor for ${target.tagName}#${target.id} should NOT be red`);
}));
test_driver.click(target);
