The form fields are now broken because we have stolen the state control away from the fields and given it to the component. The only difference between these implementations is that the working one has a key prop and the other does not. Nothing obvious will change in your browser, but if you do not use unique keys, React will log warnings to your console and your app may behave strangely!
