title: Why is text inside <head> tag rendered?
body: <p>If I put some text inside <code>&lt;head&gt;</code> tag of an HTML page, this text is rendered by popular browsers like Chrome or Firefox (see the MWE below). Is it an expected behavior?</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;!DOCTYPE html&gt;
  &lt;html lang="en"&gt;
     &lt;head&gt; Foo Bar &lt;/head&gt;
  &lt;/html&gt;</code></pre>
  </div>
  </div>
  </p>
