[Bug]: vite with pnpm code block styles not applied

[adrianaferrugento]

Describe the bug

When using MDX code blocks storybook isn't styling them accordingly. I realised this is an issue with pnpm. When I install and run with yarn everything looks as it's supposed to. Also this is only a problem in dev mode, if I build and serve with pnpm all works as expected.

```
pnpm i
```

FYI this was fixed when I manually installed the package @mdx-js/react

Thanks for the workaround, I was starting to lose my mind here. The issue seems to be related to pnpm not resolving the @mdx-js/react correctly for some reason, manually installing it did the trick for now

it didn't work here 😞

I'm back to having the same issue as well, there might be other dependencies that we are missing..

@adrianaferrugento I had the same issue and in my case pinning the version to ^2.3.0 worked:

pnpm i @mdx-js/react@^2.3.0 -D

@JReinhold for reference, here is a reproduction repository with a clean install of vite, vue3 and storybook 7.6.10.
