React: Customizable error UI in FeatureAppLoader/FeatureAppContainer

[fahrradflucht]

<FeatureAppLoader
  src="foo.js"
  renderError={error => <div>{error.toString()}</div>}
  onError={error => console.error(error)}
/>

Instead of throwing on the server we will call onError. We can remove the browser "Weiche".
