<title>CSS Test (Selectors): Modifier key doesn't make element to stop matching :focus-visible</title>

This test checks that using a modifier key does not make the element to stop matching <code>:focus-visible</code>.
<ol id="instructions">
<li>If the element that says "Focused" has a red background, then the test result is a FAILURE.</li>
<li>Press the Ctrl key.</li>
<li>If the element keeps the green outline and has not a red background, then the test result is SUCCESS.</li>
</ol>
<p id="warning">Your user-agent does not support <code>:focus-visible</code> pseudo-class, please SKIP this test.</p>
<div id="target" tabindex="0">Focused</div>
<script>
// Check that :focus-visible is supported.
test_valid_selector(':focus-visible');

target.addEventListener("focus", t.step_func(() => {
