There appears to be traffic coming from mesh2-ingress-fed-export into non-federated Bookinfo ProductPage in mesh1-system.

Configuration setup (federated bookinfo and non-federated bookinfo both in the same SMCP):

• Create (2) AWS OCP 4.7 clusters
• Install OSSM 2.1 operators on both clusters
• Run Federation demo script on the two OCPs

• Generate traffic to federated bookinfo
• Deploy non-federated Bookinfo on cluster-1, adding the bookinfo namespace to the same SMMR in mesh1-system SMCP
• Open Kiali on OCP cluster-1 in mesh1-system namespace, and then graph both the federated and non-federated bookinfo applications.
• ** Note that mesh2-ingress-fed-export shows traffic going to Productpage in non-federated bookinfo (ref the snapshot)

Is this a supported configuration? If yes, then why is there traffic from mesh2-ingress-fed-export to non-federated Bookinfo ProductPage?
