Summary

As of now, we are only integration testing this component by directly executing the main.js which is build inside the container.
However, I've tested the latest v1.12.0 release in one of my projects and directly got the issue which was fixed with #96

This ticket is to keep track that we need a more integrated way of testing this component.
