Scala 3 different schema derivation nested enum items missing

[guymers]

Given the following:

sealed trait Enum1
object Enum1 {
  implicit val schema: Schema[Any, Enum1] = Schema.gen

  sealed trait Enum11 extends Enum1
  object Enum11 {
    implicit val schema: Schema[Any, Enum11] = Schema.gen

    case object Item111 extends Enum11 {
      implicit val schema: Schema[Any, Item111.type] = Schema.gen
    }

    case object Item112 extends Enum11 {
      implicit val schema: Schema[Any, Item112.type] = Schema.gen
    }
  }

  sealed trait Enum12 extends Enum1
  object Enum12 {
    implicit val schema: Schema[Any, Enum12] = Schema.gen

    case object Item121 extends Enum12 {
      implicit val schema: Schema[Any, Item121.type] = Schema.gen
    }
  }
}

Scala 2:

schema {
  query: Queries
}

enum Enum1 {
  Item111
  Item112
  Item121
}

type Queries {
  e: Enum1!
}

Scala 3:

schema {
  query: Queries
}

enum Enum1 {
  Enum11
  Enum12
}

type Queries {
  e: Enum1!
}
