When an automatically generated notification group has 4+ persistent notifications, hitting "clear all" will cause the group to lose its automatically generated group summary notification. The solution is to count the number of notifications belonging to a specific group as well as the number of ongoing notifications. if the number of grouped notifications > min before grouping limit & the group has at least one ongoing notification, then the group summary notification will be marked as ongoing with the flag FLAG_ONGOING_EVENT. otherwise the flag will be removed.
