Is this similar to issue21478? Michael, can you please confirm this behavior and the change proposed in issue21478?

I tried out the below program as per initial report

# foo.py

from unittest.mock import patch, Mock
p = patch('requests.get', autospec=True)
manager = Mock()
manager.attach_mock(p.start(), 'requests_get')

import requests
requests.get('https://google.com')
print(manager.mock_calls)
p.stop()
print(manager.mock_calls)

# Without patch

$ python.exe foo.py

# With PR 14688 in issue21478

$ python.exe foo.py
