Extend from React.Component (instead of React.PureComponent)

Are you submitting a bug report or a feature request?

Eh, this feels kind of somewhere in the middle.

What is the current behavior?

FieldArray extends React.PureComponent.

What is the expected behavior?

FieldArray extends React.Component.

For the reasons discussed in final-form/react-final-form#150, I'd like to see parity across all react-final-form* packages.

The tl,dr: I have external state I feed into my FieldArray render component. I also have to explicitly pass this state to FieldArray as a prop, so the component re-renders.
