This seems like it might be a good place for this additional test, but if there is a better way/location, let me know.

it('should have the fullWidth prop from the instance', () => {
const formControlRef = React.createRef();
const { setProps } = render(<FormControlled ref={formControlRef} />);

expect(formControlRef.current).to.have.property('fullWidth', false);

setProps({ fullWidth: true });
expect(formControlRef.current).to.have.property('fullWidth', true);
});
});

I'm not sure this is correct or even necessary, but it seems like a type update would be good to do for anything that returns the updated context object.

| 'margin'
| 'required'
| 'variant';

export interface FormControlState extends Pick<FormControlProps, ContextFromPropsKey> {
