title: How can I add JSON highlighting to the code in Jira comment?
body: <p>Is it possible to add a highlighted code to Jira comment? I want to write something like this:</p>
  
  <hr>
  
  <p>The comment text and JSON doc:</p>
  
  <pre><code>{
    "key": 100
  }
  </code></pre>
  
  <hr>
  
  <p>I've found only one example:</p>
  
  <pre><code>{code:javascript}
  {
    "key": 100
  }
  {code}
  </code></pre>
  
  <p>But it does not really highlight my code. I see only the grey block.</p>
