Teardown duration reported in the following setup (pytest_runtest_logreport)

This simple test:

import time
import pytest

@pytest.fixture(scope="module", params=[1, 2])
def fix():
    time.sleep(2)
    yield
    time.sleep(2)

@pytest.mark.parametrize('par', [1, 2])
def test_one(fix, par):
    pass

And this conftest.py file:

def pytest_runtest_logreport(report):
    print(f"Report at {report.when}, with duration {report.duration}")

The prints I get are:

Report at setup, with duration 2.00620698928833
Report at call, with duration 0.0
Report at teardown, with duration 0.0
Report at setup, with duration 0.0
Report at call, with duration 0.0
Report at teardown, with duration 0.0
Report at setup, with duration 4.012362957000732
Report at call, with duration 0.0
Report at teardown, with duration 0.0
Report at setup, with duration 0.0
Report at call, with duration 0.0
Report at teardown, with duration 2.0061838626861572

So, basically, instead of having in the middle of test a teardown with 2 seconds and then a setup with 2 seconds, I have instead a setup of 4 seconds.

Is it normal or a bug?

Windows 10 and python 3.6 venv with only pytest 5.0.1 installed.

Reproduce the example using the shown test and conftest.py, then inspect the pytest_runtest_logreport output for setup and teardown timing. Trace fixture setup and teardown across the parametrized tests to determine whether the durations are reported correctly. Done when the behavior is confirmed as expected or a focused fix and regression test are identified.
