cordova-plugin-firebase: BUG (Android): onNotificationOpen doesn't fire when app is open and in foreground.

UPDATE: This appears to be a bug in Android only, I finally tested things on my iOS devices and everything works as expected. When iOS app is open and a push notification message arrives, the onNotificationOpen fires and I am able to process the payload and create a custom message/popup to the user. This simply does not work in Android - onNotificationOpen never fires.

In the documentation for function onNotificationOpen, the author states:

App is in foreground: User receives the notification data in the JavaScript callback without any notification on the device itself (this is the normal behaviour of push notifications, it is up to you, the developer, to notify the user)

But best I can tell, when the app is opened and a push is received, onNotificationOpen never fires, so the callback never fires.

  window.FirebasePlugin.onNotificationOpen(function(payload) {
    console.log(payload) ;
  }, function(error) {
      console.error(error);
  }) ;

If app is closed, notification arrives, user clicks on notification, app opens and fires onNotificationOpen - if a payload exists, it gets processed as payload.ObjectKey - WORKS
If app is open but in the background, the same behavior as #1. - WORKS
But if app is open and in the foreground, the notification never shows in the status bar (apparently native behavior), but what function fires? It is not onNotificationOpen - DOES NOT WORK. console.log never fires (not even the error one), thus onNotificationOpen is not firing - this is contrary to author’s documentation.

So either its a bug OR the author somehow is referring to another JS callback in his documentation.
