[@vitejs/plugin-vue] CSS has no corresponding SFC entry in the cache

• Read the docs.
• Use Vite >=2.0. (1.x is no longer supported)
• If the issue is related to 1.x -> 2.0 upgrade, read the Migration Guide first.

Describe the bug

I’ve seen #1542, #1308 and #1561 but this is still reproducible with latest vite/vue-plugin for me.

[vite] Internal server error: /Users/leben/Desktop/my-vue-app/node_modules/@vueform/multiselect/themes/default.css has no corresponding SFC entry in the cache. This is a @vitejs/plugin-vue internal error, please open an issue.
  Plugin: vite:vue
  File: /Users/leben/Desktop/my-vue-app/node_modules/@vueform/multiselect/themes/default.css?v=1214311d&vue&type=style&index=1&src&lang.css

Reproduction
