title: WKWebView remove one item from WKBackForwardList
body: <p>I'm implementing a tiny browser, so I would like to be able to navigate back and forward on my web view. For these purposes I use WKWebView, but I need to display an Error html page sometimes, and I don't want this page to be stored in my WKBackForwardList.</p>
  
  <p>Is there any way to remove one item from WKBackForwardList ?
  I guess that it is a really general issue, so, do I have to implement my own History functional?</p>
