Stylus resolve url when building Webpack?

Question

webpack

Config, as you can see &resolve url option is enabled to fix file paths,

{
            test: /\.styl$/,
            loader: ExtractTextPlugin.extract(
                `style-loader`,
                `css-loader?sourceMap!postcss-loader!stylus-loader?paths[]=node_modules,paths[]=lib&include css&resolve url`,
                {publicPath: ``}
            )
        }

Just not for fill !

Child extract-text-webpack-plugin:
        + 1 hidden modules
