No "Testsuite summary" with a subset of 'faker' tests

For some reason, no "Testsuite summary" output is generated when running the faker test suite.

A simple reproducer which skips all the other tests is to use the following in pytest.ini:

pytest.ini
[pytest]
addopts =
    --ignore=tests/mymodule
    --ignore=tests/providers
    --ignore=tests/test_*.py
    --ignore=tests/utils
    --ignore=tests/pytest/session_overrides

This results in the following output from pytest --automake:

PASS: tests/pytest/test_autouse_faker_locale.py:test_no_injection
PASS: tests/pytest/test_autouse_faker_locale.py:test_inject_faker_seed
PASS: tests/pytest/test_autouse_faker_seed.py:test_no_injection
PASS: tests/pytest/test_autouse_faker_seed.py:test_inject_faker_locale
PASS: tests/pytest/test_manual_injection.py:test_no_injection
PASS: tests/pytest/test_manual_injection.py:test_inject_faker_locale
PASS: tests/pytest/test_manual_injection.py:test_inject_faker_seed
PASS: tests/pytest/test_manual_injection.py:test_inject_faker_seed_and_locale

but there is no expected "Testsuite summary".

Ignoring the tests/pytest test cases allows the test suite to pass, with a "Testsuite summary":

[pytest]
addopts =
    --ignore=tests/pytest

Results:

# TOTAL: 2151
# PASS: 2146
# SKIP: 5
