 <p>This tests a bug when copying HTML markup inside &lt;pre&gt; tags. When pasted, this content would appear as the rendered form of that markup.
 You should see markup in the editable region below. See &lt;rdar://5027857&gt;.</p>
 <div><pre id="pre" contenteditable="true">&lt;input type='button'&gt;foo&lt;br&gt;bar&lt;b&gt;baz&lt;/b&gt;</pre></div>

 document.execCommand("Cut");
 document.execCommand("Paste");

 Markup.description(document.getElementsByTagName('p')[0].textContent);
