What is the bug that prevents Android N from requiring the use of FLAG_ACTIVITY_NEW_TASK??

see the following changes

in Android P Behavior Changes
FLAG_ACTIVITY_NEW_TASK requirement is now enforced
With Android P, you cannot start an activity from a non-activity context unless you pass the intent flag FLAG_ACTIVITY_NEW_TASK. If you attempt to start an activity without passing this flag, the activity does not start, and the system prints a message to the log.

Note: The flag requirement has always been the intended behavior, and was enforced before Android N. A bug in Android N temporarily kept the flag requirement from being enforced.

I would like to ask what bug causes Android N to prevent the mandatory addition of FLAG_ACTIVITY_NEW_TASK? to activity in non-Activity Context startup

seems to find only modification source , know bug id, but don"t know how to find detailed bug from it.

add: suspected question link , but access was denied when I checked.

as I understand it:

if your Context is not Activity and does not use FLAG_ACTIVITY_NEW_TASK before AndroidN, it will disable startup and output logs to the system

the FLAG in Android N did not take effect, resulting in a different result than expected, and the bug

has been fixed.
