HA cluster never becomes active

Hello,

I just setup a Vault in HA mode with local storage / raft using the official Helm chart. I currently have 2 replicas and both of them seems to be in good shape:

even if one of the replicas is set to active, it doesn’t have the “vault-active” label and so is not available from the vault-active service.
