title: Puppeteer: How do I open a page in a new window?
body: <p>I am trying to open a new page in a new window without launching another instance of Puppeteer (i.e. I am <em>not</em> trying to run <code>puppeteer.launch()</code> multiple times, as this would create another browser session). Is there a way I can open a new window with <code>browser.newPage()</code> or some other method from an existing browser session?</p>
