Limit for nesting Dict objects

[lokitorin]

Describe the bug:

It seems that nested models with field of type 'Dict' limits data generation:

Steps to reproduce the issue:

script to reproduce (run with streamlit run)

from typing import (Text, Dict)
from pydantic import BaseModel
import streamlit_pydantic as sp

class first(BaseModel):
    item: Dict[Text, int]

class second(BaseModel):
    item2: Dict[Text, first]

class third(BaseModel):
    item3: Dict[Text, second]

if __name__ == '__main__':

    data = sp.pydantic_input(key="test", model=third)
    pass
