### Bug description

This doesn't work on Quarto v1.3.124 on macOS 13.0.1:

    ```swift
    let foo = "bar" // <1>
    ```

    1. Test

The code block is rendered with the `// <1>` as if it were standard code, and the ordered list a standard list.

Changing the `// <1>` to `# <1>` doesn't work either. Neither does changing `swift` to `javascript`. Changing it to `python` or `r` works, but syntax highlighting is wrong.
