Note: An interesting quirk is that adding targetOrigin here will break Android native.

The latest version ~2.4.* is broken on Android. This is due to an oddity in react-native-webview/react-native-webview#356 that the addEventListener needs to be modified for Android WebView. This now fixes the issue.
The previous web version is also broken if we host the iframe on a different domain due to the cross-origin policy. This also ensures that we are more relaxed on targetOrigin.
Fixes #378
