Please Describe Your Changes

When building a library that exposes the main file exports to a variable ( for example window ) and use a multi entry config, only the last item in the entry array will be exposed. The example that was provided by the plugin would expose the webpack plugin serve client in the end file and it breaks the app.

An example of such configuration is:

// webpack.config.js
				output: {
					filename: `js/app.js`,
					library: ['zb', 'app'],
					libraryTarget: 'window'
				}
