CSS file no longer exported to /dist folder with vite@5 and vite-plugin-css-export@3

[PieterT2000]

My src folder contains an index.css file wich is imported into the lib's entry point, index.js, as

import './index.css?export'

Since vite@5, however, the index.css file is no longer exported to the /dist folder. The CSS code is also not inlined into JS bundle. @shixuanhong Any suggestions what I should do? If you need more info, please let me know.
