webpackJsonp is not defined with webpack2 and split-by-path plugin

We are using webpack2 and the split-by-path-webpack-plugin. We had to patch the plugin in order to use it with webpack2, but after building the bundle, it seems that there is still something wrong.
This is our configuration:

module.exports = {
    context: APP,
    target: 'web',
    entry: {
        bundle: './.caches/jsClient/Admin/App.js',
    output: {
        path: path.join(__dirname, 'dist'),
        filename: "[name]_[chunkhash].js",
        chunkFilename: "[name]_[chunkhash].js",
        publicPath: '../dist/',

    devtool: 'source-map',
    resolve: {
        extensions: ['.webpack.js', '.web.js', '.ts', '.js'],
    performance: {
        hints: false,

    module: {
        rules: [
//            { test: /(?!\.min)\.js$/, enforce: 'pre', loader: "source-map-loader" }
            { test: /\.css$/, loader: "style-loader!css-loader" },
                test: /\.html$/, // Only .html files
                loader: 'html-loader' // Run html loader
            { test: /.(png|woff(2)?|eot|ttf|svg)(\?[a-z0-9=\.]+)?$/, loader: 'file-loader?name=[name].[ext]' },
    plugins: [
        new Md5Hash(),
        new AssetsPlugin({update: true}),
        new ChunkManifestPlugin({
            filename: "chunk-manifest.json",
            manifestVariable: "webpackManifest"
        new SplitByPathPlugin({
            buckets: [{
                name: 'vendor',
                regex: /node_modules/,
        new WebpackCleanupPlugin({
            quiet: true,
            exclude: ["chunk-manifest.json", "Fonts/**/*"]

Both bundle and vendor files are created and we load the bundle file first, but they don’t get executed as intended.

TypeError: modules[moduleId] is undefined (bundle.js)
ReferenceError: webpackJsonp is not defined (vendor.js)

When I look at our resulting bundle, I’m unable to find any definition of the jsonp function. Does the split-by-path plugin need to do anything so the method gets defined?
This current behavior is quite confusing from a users standpoint.
