HMR with the css-loader is broken when enable modules

{ 
  test: /\.css$/,
  loaders: ['style', 'css?module&localIdentName=[hash:base64:5]']
}

css file

body{
  color: black;
}
.test{
  color: red;
}

It's not broken, HMR behaves different for modules that doesn't export stuff (normal CSS) vs. modules that does export stuff (CSS Modules).

Because CSS Modules export stuff the parent module need to accept the module. See HMR documentation.

Probably fixed in webpack-contrib/style-loader#298
