Replication Issue: Unable to Configure a Replica2 as replica of Replica1

I have three DragonflyDB servers: a master, replica1, and replica2. Replica1 is set as a replica of the master. However, when I try to make **replica2 as replica of replica1**, I get the following error:

ERR: Bad response to "REPLCONF listening-port 6379": "-ERR Replicating a replica is unsupported\r\n"

Is this expected behavior in DragonflyDB? In Redis, **I am able to configure replica2 as a replica of replica1** without any issues.

Could anyone please clarify this.?

No source file, test, or entry point is named. Start by reproducing the three-server setup and tracing the replica configuration path handling `REPLCONF listening-port`; done means establishing whether replica-of-replica replication is supported or documenting the confirmed behavior compared with Redis.
