I think it is best reporting this to hljs on GitHub, given it is an issue with the default diff implementation:

> **[Demo - highlight.js](https://highlightjs.org/demo)**
>
> Preview how highlight.js will highlight your code snippets and share them with other syntax highlighting nerds

> **[Issues · highlightjs/highlight.js](https://github.com/highlightjs/highlight.js/issues)**
>
> JavaScript syntax highlighter with language auto-detection and zero dependencies. - Issues · highlightjs/highlight.js

Discourse really can not control this easily, we simply pull the changes from upstream.
