Cannot deserialize list

[remdragon]

dataclasses_serialization.version== '1.3.1' Python 3.9.2 (tags/v3.9.2:1a79785, Feb 19 2021, 13:30:23) [MSC v.1928 32 bit (Intel)] on win32 Windows 10 Pro Version 2004, Build 19041.867

Here's what I've narrowed it down to:

from dataclasses import dataclass, field
from dataclasses_serialization.json import JSONSerializer # type: ignore # pip install dataclasses-serialization
from typing import List

@dataclass
class LogModule:
    name: str
    level: str

@dataclass
class Logging:
    modules: list[LogModule] = field ( default_factory = list )

@dataclass
class MyConfig:
    logging: Logging = Logging (
        modules = [
            LogModule ( '__main__', 'DEBUG' ),
        ],
    )

myconfig = MyConfig()
x = JSONSerializer.serialize ( myconfig )
dup = JSONSerializer.deserialize ( MyConfig, x )
print ( repr ( dup ) )
assert dup == myconfig, f'{dup=} != {myconfig=}'

produces the following output:

If I change the definition of Logging.modules from list[LogModule] to List[LogModule] then it works correctly.
