Given:

const xhtml = `
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
  <head>
    <meta http-equiv="Content-type" content="text/html; charset=utf-8" />
    <title>Test</title>
  </head>
  <body>
  </body>
</html>
`;

const { document } = new JSDOM(xhtml).window;

console.log(serialize(document));

the output will something like this:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"><html xmlns="http://www.w3.org/1999/xhtml" xmlns="http://www.w3.org/1999/xhtml"><head>
    <meta http-equiv="Content-type" content="text/html; charset=utf-8" />
    <title>Style Test</title>
  </head>
  <body>
</body></html>

So I now have the xmlns attribute twice in the html-element.
