webpack multicompile. hot-reload doesn't work

[Mr-Grp]

I use webpack to multi-compile modules, with support for hot updates. like this:

// webpack.config.js
const config = [
  {
    name: 'C1',
    entry: './src/C1.js',
    plugins: [new PreactRefreshPlugin()],
    output: {

    }
  },
  {
    name: 'C2',
    entry: './src/C2.js',
    plugins: [new PreactRefreshPlugin()],
    output: {
     
    }
  }
];
// ......
webpack(config)

As a result, the final page will have two compiled artifacts, each containing hot update related code, but it is not working properly. I feel that this may be due to different artifacts sharing the same variable(self.xxx).
