Wrong default value with enumeration derived from xs:list

[tefra]

  <xsd:simpleType name="MyEnumeration">
    <xsd:restriction base="xsd:NMTOKEN">
      <xsd:enumeration value="first" />
      <xsd:enumeration value="second" />
      <xsd:enumeration value="third" />
    </xsd:restriction>
  </xsd:simpleType>
  <xsd:simpleType name="MyEnumerationList">
    <xsd:list itemType="MyEnumeration" />
  </xsd:simpleType>
  <xsd:complexType name="Root">
    <xsd:all>
      <xsd:element name="values" type="MyEnumerationList" default="first" />
    </xsd:all>
  </xsd:complexType>

Generates

@dataclass
class Root:
    values: List[MyEnumeration] = field(
        default_factory=MyEnumeration.FIRST,
        metadata={
            "type": "Element",
            "namespace": "",
            "tokens": True,
        }
    )

It should be

@dataclass
class Root:
    values: List[MyEnumeration] = field(
        default_factory=lambda: [MyEnumeration.FIRST],
        metadata={
            "type": "Element",
            "namespace": "",
            "tokens": True,
        }
    )
