I added a test case to reproduce this issue.

I have two questions about the general workflow here:
1. If an issue is set to private, how does that happen / what does that mean? I was under the impression that all issues are public unless they are related to security or something. And the linked issue does not look like a security issue
2. How exactly is the requirement for a reproducer defined? Like if I observe that an issue is happening, but can't reproduce it manually, is a constructed test case good enough?
