Props not updated when shouldComponentUpdate returns false (lifecycleExperimental: true)

[wicked539]

When shallow rendering a component using lifecycleExperimental: true, it seems that it's props are not updated if it's shouldComponentUpdate()-method returns false. Since the props are updated in production and when using standard shallow rendering, I'm guessing that this would be the desired behavior.

import React from 'react';
import chai from 'chai';
import { shallow } from 'enzyme';

class MyDummyComponent extends React.Component {

    shouldComponentUpdate() {
        return false;
    }

    render() {
        return (<div>hello world.</div>)
    }
}

describe('<MyDummyComponent/>', function () {

    it('fails to update props with lifecycleExperimental: true', function () {
        let props = {
            foo: 'bar'
        }

        const wrapper = shallow(<MyDummyComponent {...props} />, { lifecycleExperimental: true });

        chai.expect(wrapper.instance().props.foo).to.equal('bar');

        props.foo = 'baz';

        wrapper.setProps(props);

        // fails when shouldComponentUpdate returns false, succeeds otherwise
        chai.expect(wrapper.instance().props.foo).to.equal('baz');
    });

    it('updates props with "normal" shallow rendering', function () {
        let props = {
            foo: 'bar'
        }

        const wrapper = shallow(<MyDummyComponent {...props} />);

        chai.expect(wrapper.instance().props.foo).to.equal('bar');

        props.foo = 'baz';

        wrapper.setProps(props);

        chai.expect(wrapper.instance().props.foo).to.equal('baz');
    });
});

I am using React 15.4.2 & Enzyme 2.7.1.

I'll take on this.
