 *
 * @remarks
 *
 * Accessibility is a very platform-specific thing. On different platforms,

 *
 * Blink - Chrome's rendering engine - has a concept of "accessibility tree",

 * namespace gives users access to the Blink Accessibility Tree.
 *
 * Most of the accessibility tree gets filtered out when converting from Blink
 * AX Tree to Platform-specific AX-Tree or by assistive technologies themselves.
 * By default, Puppeteer tries to approximate this filtering, exposing only
 * the "interesting" nodes of the tree.

 * Protocol methods can be called with {@link CDPSession.send} method and protocol

 * await client.send('Animation.enable');
 * client.on('Animation.animationCreated', () => console.log('Animation created!'));
 * const response = await client.send('Animation.getPlaybackRate');

 * The Mouse class operates in main-frame CSS pixels
 * relative to the top-left corner of the viewport.
 * @remarks
 * Every `page` object has its own Mouse, accessible with [`page.mouse`](#pagemouse).
 *
 * @example
 * ```js
 * // Using ‘page.mouse’ to trace a 100x100 square.
 * await page.mouse.move(0, 0);
 * await page.mouse.down();
 * await page.mouse.move(0, 100);
 * await page.mouse.move(100, 100);
 * await page.mouse.move(100, 0);
 * await page.mouse.move(0, 0);
 * await page.mouse.up();
 * ```
 *
 * **Note**: The mouse events trigger synthetic `MouseEvent`s.
 * This means that it does not fully replicate the functionality of what a normal user
 * would be able to do with their mouse.
 *
 * For example, dragging and selecting text is not possible using `page.mouse`.
 * Instead, you can use the {@link https://developer.mozilla.org/en-US/docs/Web/API/DocumentOrShadowRoot/getSelection | `DocumentOrShadowRoot.getSelection()`} functionality implemented in the platform.
 *
 * @example
 * For example, if you want to select all content between nodes:
 * ```js
 * await page.evaluate((from, to) => {
 *   const selection = from.getRootNode().getSelection();
 *   const range = document.createRange();
 *   range.setStartBefore(from);
 *   range.setEndAfter(to);
 *   selection.removeAllRanges();
 *   selection.addRange(range);
 * }, fromJSHandle, toJSHandle);
 * ```
 * If you then would want to copy-paste your selection, you can use the clipboard api:
 * ```js
 * // The clipboard api does not allow you to copy, unless the tab is focused.
 * await page.bringToFront();
 * await page.evaluate(() => {
 *   // Copy the selected content to the clipboard
 *   document.execCommand('copy');
 *   // Obtain the content of the clipboard as a string
 *   return navigator.clipboard.readText();
 * });
 * ```
 * **Note**: If you want access to the clipboard API,
 * you have to give it permission to do so:
 * ```js
 * await browser.defaultBrowserContext().overridePermissions(
 *   '<your origin>', ['clipboard-read', 'clipboard-write']
 * );
 * ```

 * Page provides methods to interact with a single tab or

 *
 * @remarks

 * One Browser instance might have multiple Page instances.
 *

 * ```js
 * const puppeteer = require('puppeteer');
 *
 * (async () => {
 *   const browser = await puppeteer.launch();

 * })();
 * ```
 *
 * The Page class extends from Puppeteer's {@link EventEmitter} class and will
 * emit various events which are documented in the {@link PageEmittedEvents} enum.
 *
 * @example
 * This example logs a message for a single page `load` event:
 * ```js
 * page.once('load', () => console.log('Page loaded!'));
 * ```
 *
 * To unsubscribe from events use the `off` method:
 *
 * ```js
 * function logRequest(interceptedRequest) {

 * }
 * page.on('request', logRequest);
 * // Sometime later...

     * The only difference between {@link Page.evaluate | page.evaluate} and
     * `page.evaluateHandle` is that `evaluateHandle` will return the value
     * wrapped in an in-page object.
     *
     * If the function passed to `page.evaluteHandle` returns a Promise, the
     * function will wait for the promise to resolve and return its value.
     *
     * You can pass a string instead of a function (although functions are
     * recommended as they are easier to debug and use with TypeScript):
     *
     * @example
     * ```
     * const aHandle = await page.evaluateHandle('document')
     * ```
     *
     * @example
     * {@link JSHandle} instances can be passed as arguments to the `pageFunction`:
     * ```
     * const aHandle = await page.evaluateHandle(() => document.body);
     * const resultHandle = await page.evaluateHandle(body => body.innerHTML, aHandle);
     * console.log(await resultHandle.jsonValue());
     * await resultHandle.dispose();
     * ```
     *
     * Most of the time this function returns a {@link JSHandle},
     * but if `pageFunction` returns a reference to an element,
     * you instead get an {@link ElementHandle} back:
     *
     * @example
     * ```
     * const button = await page.evaluateHandle(() => document.querySelector('button'));
     * // can call `click` because `button` is an `ElementHandle`
     * await button.click();
     * ```
     *
     * The TypeScript definitions assume that `evaluateHandle` returns
     *  a `JSHandle`, but if you know it's going to return an
     * `ElementHandle`, pass it as the generic argument:
     *
     * ```
     * const button = await page.evaluateHandle<ElementHandle>(...);
     * ```
     *
     * @param pageFunction - a function that is run within the page
     * @param args - arguments to be passed to the pageFunction
