title: Watir get browser html with iframe content included
body: <p>Is there a way to get the html of the whole page with rendered iframes html also included? I know you can access browser html like so.</p>
  
  <pre><code> browser.html
  </code></pre>
  
  <p>but that only prints the current's DOM html, without the iframe contents. I also know the iframe content can be retrieve like so .</p>
  
  <pre><code> browser.iframe(index: 0).html
  </code></pre>
  
  <p>But is there a way to get the browser page contents, with all the iframes content rendered included also; the reason why I'm asking is because some iframes might have other iframes embedded and so on. So it becomes cumbersome to parse.</p>
  
  <p>Thanks.</p>
