I’ve created a text viewer (right side) which dumps my own language.

If I open it in a separate file everything works well:

- highlights
- references highlights
- custom annotator

But if I open it in my editor only syntax highlights work. I’ve done the same with PHP language and there are no difference between my language and PHP

Any idea what’s going on?
