$share subscriptions and C# client per subscription callback

$share/group/topic/item
topic/item

The $share topic doesn’t fire an event when configured via SubscribeOptionsBuilder.WithSubscription, but the non-$share one does.

The $share topic DOES fire a client.OnMessageReceived event.

Is it because MatchTopic() is trying to match “$share/group/topic/item” with “topic/item” because “topic/item” is what is sent from the broker?
