Vite MPA mode generates a js file for styles (BUG)?

[ivanjeremic]

I have MPA mode and this is my config:

export default defineConfig({
  plugins: [react()],
  build: {
    rollupOptions: {
      input: {
        page1: resolve(__dirname, "page1.html"),
        page2: resolve(__dirname, "page2.html"),
        page3: resolve(__dirname, "page3.html"),
      },
      output: {
        manualChunks: undefined,
        entryFileNames: `assets/[name].js`,
        chunkFileNames: `assets/[name].js`,
        assetFileNames: `assets/[name].[ext]`,
      },
    },
    cssCodeSplit: false,
    sourcemap: "inline",
    assetsInlineLimit: 0,
  },
});

This should output only page1.js, page2.js, page3.js & style.css but it adds to that also a style.js with sourcemap in it , this style.js is unnecessary and the application works without it, is this a bug how can this be fixed?
