<p>This test checks that by default, if using JavaScript to focus an element triggers <code>:focus-visible</code> matching, then the element should show a focus ring with <code>outline-style: auto</code>.</p>

<li>Focus the following elements with the keyaboard navigation (pressing TAB), if the elements show a focus ring with <code>outline-style: auto</code>, then the test result is SUCCESS.</li>
