[Bug] failover topics behaving like shared topics when running apachepulsar/pulsar:3.0.0 standalone (only tested via python client)

### Search before asking

- [X] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar.

### Version

apachepulsar/pulsar:3.0.0

### Minimal reproduce step

run docker with `pulsar standalone` command and use a python client to create two separate consumers configured for the same topic and with a consumer type of `failover`.

### What did you expect to see?

messages should only be consumed by one of the two created consumers.

### What did you see instead?

both consumers receive messages.

### Anything else?

i downgraded to apachepulsar/pulsar:2.11.1 and things worked correctly (with no change to client version or source code).

### Are you willing to submit a PR?

- [ ] I'm willing to submit a PR!
