title: Get the html of the javascript-rendered page (after interacting with it)
body: <p>I would like to be able to save the state of the html page after I've interacted with it.</p>
  
  <p>Say I click a checkbox, or the javascript set the values of various elements.</p>
  
  <p>How can I save the "javascript-rendered" page?</p>
  
  <p>Thanks.</p>
