RollUp JS: TypeError: Cannot read property 'inputValue' of undefined

package.json

  "react-select": "^2.4.1",

File CountryPicker.js:

import React, { Component } from 'react';
import Select from 'react-select';

const options: Object = [
   {value: 'chocolate', label: 'Chocolate'},
   {value: 'strawberry', label: 'Strawberry'},
   {value: 'vanilla', label: 'Vanilla'}
];

class CountryPicker extends Component {
   render () {
     return (
       <Select options={options} inputValue={'strawberry'}/>
     );
   }
}

Usage:

class App extends React.Component {
   render () {
       return <CountryPicker/>;
   }
}

// Always starts once doom
document.addEventListener('DOMContentLoaded', () => {
   /** @type {HTMLDivElement} */
   let elm = document.querySelector('div#root');

   // noinspection ES6ModulesDependencies
   ReactDOM.render(<App />, elm);
});

And the rest:

Start with package.json and the CountryPicker.js reproduction using react-select 2.4.1, then trace the StateManager constructor shown in the stack trace. Confirm the error with the provided App example and identify the change needed so rendering no longer throws the inputValue TypeError.
