From the docs:

There's a problem with the syntax highlighting of a file

Linguist detects the language of a file but the actual syntax-highlighting is powered by a set of language grammars which are included in this project as a set of submodules as listed here.

If you experience an issue with the syntax-highlighting on GitHub, please report the issue to the upstream grammar repository, not here.
Grammars are updated every time we build the Linguist gem so upstream bug fixes are automatically incorporated as they are fixed.

If this is reproducible, then it needs to be reported to the grammar maintainers. If it's just that page, then it's likely a rendering issue outside of linguist's control and needs to be reported to GitHub's support using the Contact link at the bottom of the page.
