title: Is it possible to prevent testcafe/hammerhead scripts injection in specific iframe?
body: <p>everyone.
  What I want to do - to create an <strong>empty/pristine</strong> iframe on testcafe page.</p>
  
  <p>Problem:
  Testcafe/hammerhead injects custom script, that overrides prototypes and creates many global variables. I need to prevent it somehow. So I need to create iframe on testcafe page, but without all this custom injected stuff.<a href="https://i.stack.imgur.com/WUd50.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/WUd50.png" alt="enter image description here"></a></p>
  
  <p>Is there any API method or "hack" for this?</p>
  
  <p>I use the latest testcafe version.</p>
