Can't configure syntax highlighting in code macro

According to this it should be possible to change the syntax highlighting theme for the code macro, but I have inserted the line “” into my and rebooted the server with no change at all. This issue says it’s been fixed, am I just missing something?

I did the following and it works well for me:

  • added at the end of file
  • restarted

I added it to the beginning of the file and restarted, with no change in highlighting

Any other suggestions?
