AnyOf[NoneField, SerializableField] does not serialize correctly

[alex-vayu]

from typedpy import SerializableField, ImmutableStructure, String, Deserializer, Serializer, NoneField, AnyOf
class TestSerializable(SerializableField):
    def serialize(self, value):
        return value.rstrip()
    def deserialize(self, value):
        return value + "  "
class Container1(ImmutableStructure):
    field1: String
    field2: AnyOf[NoneField, TestSerializable]
class Container2(ImmutableStructure):
    field1: String
    field2: TestSerializable
f = {"field1": "val1", "field2": "val2"}
f2d = Deserializer(Container2).deserialize(f)
f2s = Serializer(f2d).serialize()
assert f2s == f
f1d = Deserializer(Container1).deserialize(f)
f1s = Serializer(f1d).serialize()
assert f1s == f

Traceback (most recent call last):
  File "<input>", line 32, in <module>
AssertionError

print(f1s)
{'field2': 'val2  ', 'field1': 'val1'}
print(f2s)
{'field2': 'val2', 'field1': 'val1'}
