@ljharb Hi, I have added a unit test for this. Please kindly review.

@ljharb Hi, any chance this commit could get merged? I believe the unit test error is not caused by changed code. Re-run the test might fix the issue.
Let me know if there is anything I can improve

@laysent I'm unable to rerun appveyor tests; if you rebase and force push, that will trigger a rerun.

@laysent please rebase from the command line; the UI "update" button creates a merge commit.
