This is specific to setup described [here](https://github.com/nats-io/nats-server/issues/3191#issuecomment-1296974382) and does not require JetStream to be reproduced. The added test reproduces the above setup but without JetStream enabled in the accounts. Each cluster has a leafnode for a given account to the other cluster. The accounts import/export a subject. When a consumer is connected to cluster "B" and the producer is on cluster "A" there was a duplicate message. Due to shadow subscription caused by the import/export rules, an additional subscription was sent across the leafnode. Resolves #3191 Signed-off-by: Ivan Kozlovic <ivan@synadia.com>
