            Priority: Critical


Same app works on iOS 9 and Android. Also works on _system with Safari browser.

Use case. I create a simplified test case with a touch button to invoke code (I have tried many workarounds without change of behavior)  The fundamental code is:
----
    var options = {
      location: 'yes',
      clearcache: 'yes',
      toolbar: 'yes'
    };
      IABRef = cordova.InAppBrowser.open(encodeURI('https://conconn-staging.herokuapp.com'), '_blank', options);
 
      IABRef.addEventListener('exit', iabClose);
----

I can enter the browser. If I hit "done" immediately, I return successfully and can use the button to reinvoke the browser. However if I interact with the browser content, there is about a 90%+ that upon exit ("done") to the app, the app will not be responsive.. It should be noted that the exit listener does activate, but I have not found a way to reactivate the application's response.

I suspect that there is an interaction at the interface between InAppBrowser and the Apple Library for iOS 10, but this is speculation. As I said this work with iOS 9 and fails in iOS 10. This can be simulated . (Xcode 8.3.3)  and observed on hardware.

I believe there are multiple people facing this issue. Happy to provide more information or collaborate if appropriate.

I would be happy with a reliable work around or patch.
