Bug fix: Only when displaying a content extension while in the app (on top of app), a sec- ond notification using the same content extension arriving while view the extension, would attempt to use the current content extension. This is perhaps an iOS feature, but it is strange that the feature only happens if content extension is called from a notification that is touched while in the app and behaves differently when touched in the notification center. In practice this would only affect users when notification are send very close together (as when testing!).
