Tree shaking for cross-module inlined enum values does not work

Describe the bug

I want to use const enums instead of enum to optimize transpiled code, but it only works in a single file. When I use ESM import/export syntax for cross-module inlining, it does not work. I have tried to use rollup to implement this, and it can work. And now I want to know if this is a bug of Vite.

Would you provide a reproduction of this?
