passing test fails if run in Windows on GH actions

[qci-amos]

I have a set of tests I run with pytest in my Windows build in on GH Actions.

I originally wrote this up as a pytest issue:
pytest-dev/pytest#9321
you can see some discussion there about the perspective from pytest.

but now it looks like it's a flaky issue since if I skip the test that's been marked with flaky, then the test passes.

from that issue above, the stdout for my pytest looks like this:

Hi, did you solve this issue yet? Curious for the solution

I don't know how to solve this issue, so I just skipped it:

    if sys.platform == "win32":
        pytest.skip("this test doesn't work on GH actions on Windows?")
