 *
 * - {@link PageEmittedEvents.FrameAttached}

 * @Example
 * An example of dumping frame tree:

 * ```js
 * const puppeteer = require('puppeteer');
 *
 * (async () => {
 *   const browser = await puppeteer.launch();
 *   const page = await browser.newPage();
 *   await page.goto('https://www.google.com/chrome/browser/canary.html');
