/**
 * Dispatches an event on the passed element.
 * @param {!Element} element The DOM element to dispatch the event on.
 * @param {string} eventType The type of event to dispatch.
 * @param {Object|string=} eventName A string name of the event constructor
 *     to use. Defaults to 'Event' if nothing is passed or 'CustomEvent' if
 *     a value is set on `initDict.detail`. If eventName is given an object
 *     it is assumed to be initDict and thus reassigned.
 * @param {Object=} initDict The initialization attributes for the
 *     event. A `detail` property can be used here to pass custom data.
 * @return {boolean} The return value of `element.dispatchEvent`, which will
 *     be false if any of the event listeners called `preventDefault`.
