[Bug]: @storybook/web-components-vite `RollupError: Unexpected token` in mdx

Describe the bug

In an MDX file, I am writing documentation. Certain fenced code blocks with backticks result in a RollupError and as a result I am unable to build the storybook.

This bug appeared in my monorepo. I was able to reproduce in a fresh project using npx storybook init.

Maybe there is something I'm missing in my vite.config.js or package.json?

To Reproduce

npx storybook init and follow the prompts:

• Select vite and web components

Then update Introduction.mdx to

import { Meta } from '@storybook/blocks';

<Meta title="Example/Introduction" />

```js
/** @type { import('@storybook/web-components-vite').StorybookConfig } */
const config = {
  stories: ["../stories/**/*.mdx", "../stories/**/*.stories.@(js|jsx|ts|tsx)"],
  addons: ["@storybook/addon-links", "@storybook/addon-essentials"],
  framework: {
    name: "@storybook/web-components-vite",
    options: {}
  },
  refs: {
    example: {
      title: "example",
      url: process.env.NODE_ENV === "development" ? "http://localhost:6007/" : "example/"
    }
  },
  docs: {
    autodocs: "tag"
  }
};
export default config;
```
