This must be the most unnecessarily awkward way of doing it (have to do it from the console after navigating to the site, so the request is allowed).

    fetch("https://heydonworks.com").then(x => x.text()).then(x => { 
      var f = document.createElement("iframe"); 
      document.body.append(f); 
      f.style.left = "0px";
      f.style.top = "0px";
      f.style.width = "100%";
      f.style.height = "100%";
      f.style.position = "absolute"; 
      f.style.border = 0;
      x = x.replace(/\<\/?noscript\>/gi, ""); 
      x = x.replace(/\<script\>.*\<\/script\>/gi, ""); 
      f.contentDocument.write(x); 
    });
