COND_InitialOnly doesn't apply to subobjects' properties created after the owning actor's initial replication

Using a replicated subobject with a replicated property using the COND_InitialOnly replication condition, after an actor has performed its initial replication create a new instance of this subobject on the actor and replicate it.
Expected: Because this is the initial replication of the subobject, the COND_InitialOnly property will be replicated.
Actual: The bNetInitial RepFlag is only set for the actor's initial replication, so this property is never replicated.
