These are running at tests on the wk1 bots with out expectations files and are not real tests.
Skipped the test that seems to be causing this to happen in https://trac.webkit.org/changeset/261244/webkit
Turns out that the test I skipped was not the only one that could cause this to happen. Added a skip for these two non-test files in r272061.
Closing this bug since it is an issue beneath WebKit, fixed in Big Sur.
