Could be. We're looking at how to fix this moving forward. The tidy solution seems difficult to apply to clang-doc, since we don't encapsulate execution of the tests in a python script like that. I'm wondering if this works in the internal shell, since IIRC the pr that introduced that test passed on the GH action for windows...
