lib/helper/WebDriver.js:3025–3037

* Mimic Array.filter() API, but with an async callback function. * Execute each callback on each array item serially. Useful when using WebDriver API. * * Added due because of problem with chrome driver when too many requests * are made simultaneously. https://bugs.chromium.org/p/chromedriver/is

(array, callback)

 * @return {Promise<Array>} - Array of values.
