enum yamlcodec fails roundtrip test

[lbialy]

import org.virtuslab.yaml.*

enum Rule derives YamlCodec:
  case Allow(ip: String)
  case Deny(ip: String)
  case DenyAll
  case AllowAll
  
scala> List(Rule.Allow("192.168.0.1"), Rule.Deny("192.168.1.1")).asYaml.as[List[Rule]]
val res2: Either[org.virtuslab.yaml.YamlError, List[Rule]] = Right(List(Allow(192.168.0.1), Allow(192.168.1.1)))

scala> List(Rule.Allow("192.168.0.1"), Rule.Deny("192.168.1.1"), Rule.DenyAll).asYaml.as[List[Rule]]
val res3: Either[org.virtuslab.yaml.YamlError, List[Rule]] = Left(org.virtuslab.yaml.ConstructError: Cannot parse ScalarNode(,CoreSchemaTag(tag:yaml.org,2002:null),Some(Range(Position(45,5,0),Vector(- ,   ip: 192.168.0.1, - ,   ip: 192.168.1.1, - , ),None)))

I think encoding of enums is plain broken as it seems to loose discriminator information:

scala> List(Rule.Allow("192.168.0.1"), Rule.Deny("192.168.1.1"), Rule.DenyAll).asYaml
val res4: String = "-
  ip: 192.168.0.1
-
  ip: 192.168.1.1
-
