In the past I've worked on really difficult bugs that took days to debug only to find a super simple and trivial one-line fix at the end of that hard road. That is, 90% of the effort was understanding what was happening well enough to write that one line of code. It seems to me that 90% of the effort for this fix was contributed by the author of this post and the 10% effort of writing, testing and verifying the few-line fix was contributed by the maintainer. At the very least it seems the original author should have got a Co-Authored-By attribution, even if no lines of his original patch made it into the final commit.
