Describe the bug

As the title suggests, @shikijs/transformers doesn't seem to work with Astro. I tested this with my own repo, AstroPaper, and Astro's minimal blog starter template.

Code snippets like // [!code ++] are rendered as plain text instead of being processed. I’ve created a branch where you can check out and test the issue. After setting up the local environment, you can visit this URL to see the result.

@rishi-raj-jain Unfortunately, it doesn't work well with AstroPaper.

I'd suggest you to report to astro instead.
