<p>This test checks that a script focus after a mouse click does match <code>:focus-visible</code>.</p>
<ol id="instructions">
  <li>Click in some part of the page other than the element that says "Focused".</li>
  <li>If the element that says "Focused" has a red background then the test result is FAILURE, if it has a green outline 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>
