UserNotifications Framework

Summary:
If a notification content extension has an action that requires authentication and also defines the didReceiveNotificationResponse:completionHandler: in the view controller,  didReceiveNotificationResponse:completionHandler is not called from a locked screen.

The notification content extension disappears, but the notification banner remains on an unlocked lock screen. Subsequently responding to the notification from the unlocked lock screen works as expected.

Steps to Reproduce:
Create a notification content extension target for your app. Define the didReceiveNotificationResponse:completionHandler: function in the view controller of the notification content extension.

The corresponding category for the notification content extension should contain an action that requires authentication.

Attempt to respond to the notification from a locked screen with the action that requires authentication.

Expected Results:
After the fingerprint prompt, the notification should disappear, and the response should be forwarded to the main application.

Actual Results:
After the fingerprint prompt, the notification alert/banner remains on the unlocked lock screen, and the response is not forwarded to the main app. (Because didReceiveNotificationResponse:completionHandler: is never called).

Version/Build:
iOS 11 GM

Configuration:
iPhone 7 and iPhone 6 with iOS 11 GM. Should be reproducible on any device.

I've attached a demo project with the bug. It contains a "working" and "buggy" notification content extension. The "working" extension does not define didReceiveNotificationResponse:completionHandler:, and the "buggy" extension does.
