It is so strange to me when people get downvoted for suggesting a possible solution is to volunteer some effort. HN is all about open source until someone mentions creating a PR or even just a simple issue. Is this forum the definitive spot for complaining about software?

Filing an issue on GitHub is the correct thing to do. It has higher visibility for a longer period of time than a hacker news comment and is more likely to resolve the issue while wasting less time of the maintainer's and anyone else using the software.

edit: It seems you've been upvoted back to normal. Ignore me.
