This test checks that using the keyboard in a way that does not move focus still causes <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>Use the mouse to focus the element below that says "Click me."</li>
<li>If the element has a red outline, then the test result is FAILURE.</li>
<li>Press the ENTER key.</li>
<li>If the element now has a green outline and not red background, then the test result is SUCCESS.</li>
</ol>
<div id="one" tabindex="0">Click me.</div>
