SassError: Can't find stylesheet to import when it contains @forward with _index file

Describe the bug

10:13:27 AM [vite] Internal server error: Can't find stylesheet to import.
  ╷
1 │ @use "@material/chips/mdc-chips";
  │ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  ╵
  src/styles/index.scss 1:1  @import
  src/App.vue 3:9            root stylesheet
  Plugin: vite:css
  File: /Users/***/styles/index.scss
  Error: Can't find stylesheet to import.
    ╷
  1 │ @use "@material/chips/mdc-chips";
    │ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    ╵

The _index.scss of this dep contains @forward rules.

More information:

There is the same problem in webpack, but can be solved like this, but I haven’t see options like this in Vite’s documentation.

Reproduction

1. yarn add @material/chips@canary
2. In a new Vue3 template project.
3. @use the dep’s style following documentation:

<style lang="scss">
@use "@material/chips/mdc-chips";
</style>
