Syntax highlighting in a code block with more than one annotation

[barafael]

Say I have this code block:

```rust, no_run, my-context

```

In this case, syntax highlighting does not work. If rust is the only thing after

```

, then of course it does work.

Is this by design, or can it be configured somehow?

CommonMark, the normative spec of Markdown, treats the first word that is following to the fence ``` as the language for syntax highlighting. , is not treated as a delimiter of the language so the code block uses the unknown rust, language to highlight, not rust language.

If possible, you should remove the comma following to rust language string, like this:

```rust no_run, my-context

```

See also: markdown-it/markdown-it#626 (comment). This thread makes clear that , is not allowed in CommonMark.

Thank you for clarifying!
