>                 URL:
>             Project: Apache Cordova
>          Issue Type: Bug
>          Components: Plugin WKWebViewEngine
>    Affects Versions: 4.2.1
>         Environment: iOS 9

> When trying to communicate between an iframe and the main window using Window.postMessage()
I get the error:
> {{Blocked a frame with origin "null" from accessing a frame with origin "null"}}
> This only happens from the iframe to the main window, when communicating the other way
around it works fine.
> Both files are run locally. The error only happens after adding the plugin {{cordova-plugin-wkwebview-engine}}.
When using UIWebView the error does not happen.
> The weird thing is that this error is shown exactly 11 times, but the message goes through
anyway. See this screenshot taken from Safari while using the simulator:
You can see the MessageEvent happening at the end.
> I have added {{sandbox="allow-same-origin allow-scripts allow-popups allow-forms"}} to
the iframe tag but it didn't fix it.
> This is the code that listens to the message:
> {{window.addEventListener("message", eventHandler, false);}}
> And this is the code that emits the message from the iframe:
> {{parent.postMessage(something,"*")}}
