Zendesk REST API // html_body not working proprerly when creating a ticker

Hello,

I am trying to create a ticket with html_body content (post request). Concretely, I am trying to replicate this behaviour.

https://stackoverflow.com/questions/4615500/how-to-start-a-new-list-continuing-the-numbering-from-the-previous-list

As far as I understood, the only thing I need is to make sure is that the inside "" are treated correctly when transforming HTML into JSON:

<ol>
  <li>You can't touch this</li>
  <li>You can't touch this</li>
</ol>
<p>STOP! Hammer time.</p>
<ol start=\"3\">
  <li>You can't touch this</li>
</ol>

As actually stated here: https://developer.zendesk.com/documentation/developer-tools/getting-started/working-with-json/#converting-data-in-your-code-to-json

However, the result does not render the 3, it ignores the  It  till restarts the list. 

Is it a known limitation?
