Preview button code highlight rendering problem

[Gitawake]

In Django's admin page, I preview the sample code after using it. The code is not highlighted.

This is the picture in the input box

Same for me. Did you find a solution?

Apparently advcode plugin for Tinymce is a premium paid feature, which you can only acquire if you purchase a $30 a month "Essentials" package.

Solved it by applying highlights.js JavaScript at the top of my template like this:

<link rel="stylesheet"
      href="//cdnjs.cloudflare.com/ajax/libs/highlight.js/10.7.1/styles/default.min.css">
<script src="//cdnjs.cloudflare.com/ajax/libs/highlight.js/10.7.1/highlight.min.js"></script>
<script>hljs.initHighlightingOnLoad();</script>
