How to support umd format export default ?

[watsonhaw5566]

it will be appear "TypeError: default is not a constructor" when use export default way on build script "dist".

I found the webpack issue webpack/webpack#8480 . it suggest use 'output.libraryExport: "default" 'config but it alse no work in Rslib

minimal repo on here https://github.com/watsonhaw5566/rslib-umd-repo

See https://rspack.rs/config/output#outputlibraryexport.

export default defineConfig({
  // ...
  tools: {
    rspack: {
      output: {
        library: {
          export: 'default',
        },
      },
    },
  },
});
