Inheritance Behavior: Applies to all Items

The 'Applies to all Items' inheritance behavior does not work exactly how you'd expect. For folders (and other non-file nodes) Governance settings inherited with this behavior, the setting doesn't actually ever expire, so the expiration action will never occur.

The reason this is happening is because the inheritance behavior on the dbTriggerToNode is not set to none, and we only expire time triggers when the inheritance behavior on dbTriggerToNode is set to none. 

Changing what the inheritance behavior is set to on dbTriggerToNode could have cascading effects and be quite risky to change, so we have selected to not categorize this as a bug, but instead the intended design.
