Can't imagine the pain to even discover this problem. It normally takes me a long time to be like, "maybe I didn't make a mistake, and I have a third party bug?". Third party bugs are always the most annoying to me, usually the longest to diagnose and then ultimately I have to just tell my boss I can't do anything to fix it, but hopefully I can find a way to avoid it.
"More experienced programmers know very well that the bug is generally in their code: occasionally in third-party libraries; very rarely in system libraries; exceedingly rarely in the compiler; and never in the processor."
Sometimes I've had a pr merged. Sometimes I've had stubborn maintainers that think that their project should not follow common domain standards for /shrug reasons.
And then many other times I honestly don't have the knowledge to be able to contribute into large third party systems and it seems very rare to get an issue resolved without submitting a pr.
And lastly sometimes it's hard to judge if unexpected behavior is really a 'bug'. Similar to the last point, it can honestly be hard to tell the difference sometimes.
