title: AMP-state doesn't work with AMP.navigateTo()
body: <p>I am trying to use an amp-state for the target in AMP.navigateTo() but it doesn't bind it.</p>
  
  <p>you can see an example for the issue here: <a href="https://jsfiddle.net/omartoma/qzbfaest/1/" rel="nofollow noreferrer">https://jsfiddle.net/omartoma/qzbfaest/1/</a>
  once you click on the button, there is an exception in the console saying</p>
  
  <p><code>Uncaught (in promise) Error: Target 'null' not supported.​​​</code></p>
  
  <p>Is there any workarounds to make it work or any suggestions?</p>
