default_factory does not create new instance of an object

[soapun]

Describe the bug Default factory doesn't seem to create new instance of an object I have been using it in an inherited type. Recently found out all child objects to share the same instance as an attribute.

To Reproduce

from dataclasses import dataclass, field
from typing import Dict
import random
import dacite

def default_factory():
    print(random.randint(1, 10))
    return dict()    

@dataclass
class Dummy:

    name : str
    params : Dict = field(default_factory=default_factory)

if __name__ == "__main__":

    x = dacite.from_dict(data_class=Dummy, data={"name" : "x"})
    y = dacite.from_dict(data_class=Dummy, data={"name" : "y"})
    z = dacite.from_dict(data_class=Dummy, data={"name" : "z"})

    print(id(x.params), id(y.params), id(z.params))

Prints out

8
1905804998592 1905804998592 1905804998592

Expected behavior Expected to print 3 randints and 3 different ids. If fact only one randint is being printed and all ids are the same

Environment

• Python version: 3.9.6
• dacite version: 1.8.0 (broken), 1.7.0 (working)
• OS : Windows 10

Additional context Works in 1.7.0

+1 for the same issue after a version upgrade. Downgraded to 1.7.0 and things work again. (Python version 3.8.16, OS: macOS Ventura 13.2 on Apple M1)
