6.4.4-1.fc36


Steps to Reproduce:
For local testing:

$ mock -r fedora-rawhide-x86_64 --addrepo=https://download.copr.fedorainfracloud.org/results/ksurma/pygments-2.11.2/fedora-rawhide-x86_64/ --no-clean your.src.rpm
$ mock -r fedora-rawhide-x86_64 --addrepo=https://download.copr.fedorainfracloud.org/results/ksurma/pygments-2.11.2/fedora-rawhide-x86_64/ shell

Actual results:

    def test_style_defs():
        style_str = Snippet.style_defs()
        expected_styles = load_fixture("snippet.css").strip()
    
        # Check that a sample of the styles are present
        # (use only a sample to make the test more robust
        # against Pygments changes).
        for expect_line in expected_styles.split("\n"):
>           assert expect_line in style_str
