Describe the bug

Props are not updated in the build files when they are imported from another file when using vite build with --watch.

The problematic component is the Button, the other Components (Card & Foo) are working correctly.

Reproduction

https://stackblitz.com/edit/vitejs-vite-k4f9th7e?file=src%2Fcomponents%2FButton%2Ftypes.ts

Steps to reproduce

1. Wait until npm packages are installed
2. Run npm run start
3. Look into dist/test-components.js every prop is build correctly.
4. Change a prop in /src/components/Button/types.ts -> Vite triggers a rebuild
5. Look into test-components.js -> Button props have not been updated
