Issue Summary

In the new editing experience, by using the C# (currently listed as CSharp) for syntax highlighting in the Code Block macro, it will not work/highlight the code specifically.

Steps to Reproduce

1. Create or edit an existing page with the new editing improvements.
2. Add a Code-Block/Code Snippet macro and add a code with the C# language
3. Select C# (CSharp) as the syntax highlighting
4. Publish the Page

Expected Results

The code should be highlighted according to the selected language.

Actual Results

No highlight is applied. The code is displayed as pure text within the macro.

Workaround

Currently, there is no known workaround for this behavior. A workaround will be added here when available
