/**
 * This mock is a combination of jest-matchmedia-mock
 * https://github.com/dyakovk/jest-matchmedia-mock and
 * mq-polyfill https://github.com/bigslycat/mq-polyfill.
 *
 * A solution which allowed resizing and a more realistic implementation of
 * matchMedia was the reason for its creation. Neither project provided a good
 * solution. Combining their strong points does. The class will listen for a
 * resize event which is provided by a resizeTo function defined in the test:
 *
 *  window.resizeTo = function resizeTo(width, height) {
 *    Object.assign(this, {
 *      innerWidth: width,
 *      innerHeight: height,
 *      outerWidth: width,
 *      outerHeight: height,
 *    }).dispatchEvent(new this.Event('resize'))
 *  }
 *
 * Listeners are only called if there has been a change in the match
 * status for their media query.
