Answer:

The constructor does not pass its props to the super class. It should include the following line:
constructor(props) {
  super(props);
  // ...
}
The event listener (when assigned via addEventListener()) is not properly scoped because ES2015 doesn’t provide autobinding. Therefore the developer can re-assign clickHandler in the constructor to include the correct binding to this:
constructor(props) {
  super(props);

class SubmitButton extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      isFormSubmitted: false
    };
    this.handleSubmit = this.handleSubmit.bind(this);
  }

  handleSubmit() {
