[Bug] Cannot work when using with `@import 'tailwindcss/utilities.css'` in .scss

Details

When using this plugin with:

1. @rsbuild/plugin-sass
2. Using @import in .scss
3. Disabling lightningcss-loader

@import 'tailwindcss/utilities.css';

.foo {
  color: red;
}

The tailwindcss could not work properly.

Debugging with Rsdoctor, it shows that the semicolon is removed by sass-loader.

Reproduce

https://github.com/colinaaa-reproductions/rsbuild-plugin-tailwindcss-scss-import

• pnpm install
• pnpm build

Then, checkout the output CSS in dist, it would be something like:

@tailwind utilities.foo{color:red}

Use the linked reproduction as the starting point: run pnpm install and pnpm build, then inspect the generated CSS in dist. Focus on the interaction between @rsbuild/plugin-sass, .scss @import, disabled lightningcss-loader, and sass-loader; done means the Tailwind utilities import remains separate from the following .foo rule in the output.
