title: Why are WKNavigationDelegate methods not called on some websites?
body: <p>So i want to update some properties like the <code>UITextField</code> that holds the <code>URL</code> in my application but <code>WKNavigationDelegate</code> methods are not being called some website like youtube when I press on a specific video for example. </p>
  
  <p>I have tried adding a <code>Timer</code> that updates the <code>UITextFiled</code> every 5 seconds which worked but it's not instant and not efficient is there any other way ?</p>
