Topic Operator's internal Topic created with replication.factor of 1 and min ISR of 2

Issue

• We have a 3 node Kafka cluster on OpenShift 4.6 running that was recently updated from AMQ Streams 1.6.0 to 1.7.0.

__strimzi-topic-operator-kstreams-topic-store-changelog is created with replication.factor of 1 and min.insync.replicas of 2.

Topic: __strimzi-topic-operator-kstreams-topic-store-changelog  PartitionCount: 1       ReplicationFactor: 1    Configs: min.insync.replicas=2,cleanup.policy=compact,segment.bytes=67108864,message.format.version=2.1-IV2,min.compaction.lag.ms=0,message.timestamp.type=CreateTime,retention.bytes=209715200
        Topic: __strimzi-topic-operator-kstreams-topic-store-changelog  Partition: 0    Leader: 2       Replicas: 2     Isr: 2

• Kafka Config default.replication.factor is 3 and min.insync.replicas is 2.

• Do I need to manually update this topic operator internal topic to have additional replicas? I expected this to honor the broker's default replication factor.
