Highlights not working

[AFXcrush]

I really love the Styri color theme and syntax, but the highlights in the comments don't work. I already check if language-gfm is active, and it is. I tried with other themes and work properly, just have the issue with Styri.
Please solve that problem. I really love using Styri.

Can you provide a reproducible example? What do you expect to happen?

For example. This is simple code using another Syntax:

And this one is using Styr

No highlights

If you're using Regex parsers then you can add this to Atom's stylesheet ~/.atom/styles.less:

.syntax--comment.syntax--html .syntax--storage {
  color: purple;
}

Thanks! It made it work.
Any idea on how can I add custom highlights? As the previous image, I'd like to highlight the lines in the comments

If you want to tweak the highlighting you can find the relevant scopes with the command palette.
Press Ctrl + Shift + P and search for Editor: Log Cursor Scope to list the scopes at your cursor.
