title: Stop html from being rendered inside code blocks
body: <p>My problem is that HTML is being rendered inside code tags.
  In ghost blog I have had no issues using code tags.
  Except from HTML, which is actually rendered.  </p>
  
  <p>This example from below is actually <em>rendered</em>.</p>
  
  <pre><code>&lt;pre&gt;&lt;code&gt;
  &lt;div&gt;some text&lt;/div&gt;
  &lt;input value="even this is rendered"&gt;&lt;/input&gt;
  &lt;/code&gt;&lt;/pre&gt;
  </code></pre>
  
  <p>If I use 4-spaces inline it works fine.
  I'm using the default style layout.</p>
  
  <p>Looking at the official markdown-documentation this is supposed to work.
