Application reports state in iOS 11 as Active when app handles push notification while in Inactive state

Number:rdar://34332569 Date Originated:8 September 2017

Product:iOS Product Version:11 beta 10 (15A5372a)
Classification:Bug Reproducible:Yes
UserNotifications Framework

An app, running on iOS 11, that handles push notifications while in the Inactive state (for example, if the app was Active when the Notification Center drawer is displayed), reports it's state as Active if it handles a push notification in response to a user tapping a notification for that app.

Steps to Reproduce:
The attached sample application reproduces this problem.  It prints the state of the application in application(_:didReceiveRemoteNotification:).  It can be reproduced on iOS 11 by executing the following steps:

1. Run the app.
2. Put the app into the background
3. Send two (or more) unique push notifications to the notification token printed on the console
4. Tap one of them to open the app, 
3. Check the state reported by the app during application(_:didReceiveRemoteNotification:). 
4. Notification Center
5. Tap the second (or another) notification. 
6. Check the state reported by the app during application(_:didReceiveRemoteNotification:). 

Expected Results:
Both steps 3 and 6 above should report Inactive as the app state (this is true on iOS 10.3.3)

Actual Results:
Step 3 reports the application state as Inactive (as expected), but at step 6, the app reports its state as Active.

Try to upgrade your iPhone to iOS 11.2

This issue is gone when I upgraded my iPhone device from iOS 11.1 to iOS 11.2
