    compiler.hooks.thisCompilation.tap(this.plugin, (compilation, params) => {
        compilation.dependencyFactories.set(
            SingleEntryDependency,
            params.normalModuleFactory
        );
    });
    compiler.hooks.make.tapAsync(this.plugin, this.make.bind(this));
}, this);

How Do We Reproduce?

Just use the latest commited version of karma-webpack.
