Include active_history when propagating attribute listeners
Fixed issue where the :paramref:`.AttributeEvents.active_history` flag
would not be set for an event listener that propgated to a subclass via the
:paramref:`.AttributeEvents.propagate` flag. This bug has been present
for the full span of the :class:`.AttributeEvents` system.
Fixes: #4695
