The minimum configuration is as follows:

moduleFederation: {
    options: {},
  },
  output: {
    polyfill: 'entry',
    overrideBrowserslist: ['chrome 70'],
  },

At this time, corejs injection does not take effect.

In addition, this seems to be a problem with rspack, webpack is ok

Hello @nanianlisao. Please provide a reproduction repository or online demo. For background, see Why reproductions are required. Thanks ❤️

You can find the core-js code in this chunk:

The default lib-polyfill chunk will not be generated when using moduleFederation.options, see https://rsbuild.dev/config/module-federation/options

@chenjiahan You need to run it under chrome 70, and then the following error will appear.

The problem is that the polyfill does not take effect, not the splitChunk rule.
