@edvbld Thanks Erik,

That test is being skipped when running on Windows and I'm seeing a lot of "STANDARD_ERROR"s in the build log for the workflow, so not sure if this was a false negative.

I gave the latest version a run on WSL. There are a lot of failing tests if I do that, unrelated to this PR, but at least the particular test is now passing.
