title: Getting unexpected output when tried to markup h1 inside i tag inside h1 tag
body: <p>I am Having little confusion for the output I am getting while I tried the following code:</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;h1&gt;something&lt;/h1&gt;
  
  &lt;h1&gt;
    &lt;i&gt;
      &lt;h1&gt;something&lt;/h1&gt;
    &lt;/i&gt;
  &lt;/h1&gt;</code></pre>
  </div>
  </div>
  </p>
  <p>As you may see the output generates text with font size much bigger than usual h1 tag, Can you please suggest any reason for it or any mistake I have made in it?</p>
