I only started noticing this one with 4.4.1+ build 20240719 reminding me that I needed to install php_tidy for the  HTML Tidy filter to actually work.

If you have HTML Tidy enabled, its adds <![CDATA[ ]]> tags inside the script element, breaking any code that might be there.

Steps to reproduce:

• On a course, ensure the HTML Tidy filter is enabled.
• To that course, add a page resource.
• In the page content, ensure you are viewing the source code (or use plain text editor)
• Add the following script

<script>

  console.log('Hello World!');

</script>  

• Save and display the page.
• In the browser console, note the error Uncaught SyntaxError: expected expression, got '<'
• View the error code to see the following:

<script>

   [CDATA[    console.log('Hello World);

  ]]>

  </script>  

• Disable the HTML Tidy filter for this course.
• View the page resource again and see the correct output in the console.

As a potential solution, I do wonder if this filter should have output-html => true and output-xhtml => false ?
