Custom markers don't show custom color in 'short test summary info' section

At the end of a pytest run, you have a section called "short test summary info," which terminates in a single line that shows final metrics, all color-coded according to outcome. It doesn't appear as if this final line uses the custom color to color-code tests that are marked with custom markers. I do see that the initial "test session starts" section does color-code those tests, however.

Am I missing something or is this a deficiency in the final section processing code? I'd like to see that final line show my 'snowflake' tests in cyan!

Output:

pytest.ini:

[pytest]
markers =
    snowflake: mark a test as flaky (may pass, may fail)

plugin.py:

def pytest_report_teststatus(report: TestReport, config: Config):
    """Put snowflake tests into a separate group from other failures."""
    if report.when == "call" and 'snowflake' in report.keywords.keys() and report.keywords["snowflake"]:
        return 'snowflake', '❄', ('SNOWFLAKE', {"cyan": True})

test1.py:

def test_aa_ok():
    print("This test doesn't have much to say, but it passes - so OK!!")
    pass

test2.py:

def test_aa_ok():
    print("This test doesn't have much to say, and it fails - not OK!!")
    assert 0

test_snowflake.py:

@pytest.mark.snowflake
def test_snowflake_1():
    assert True


@pytest.mark.snowflake
def test_snowflake_2():
    assert False

Reproduce the report using the supplied pytest.ini, plugin.py, test1.py, test2.py, and test_snowflake.py examples. Start by comparing marker coloring in the test-session output with the short test summary info section. Done means custom markers retain their configured cyan color in the final summary line, with coverage for both passing and failing snowflake tests.
