Not to make excuses for plagiarism, I am looking at the code itself and somewhat scratching my head since it seems quite...trivial?

I don't mean to belittle the effort but at least in terms of volume of code and level of effort, I wouldn't recognize it as mine if someone had copied it from my work and passed it off as theirs.

Regarding the charge of plagiarism, is it possible that the PR attribution reflects someone eager to contribute something to a larger effort as opposed to simply trying to "steal" someone else's work?

One could reasonably interpret the PR and attribution as "I integrated this code into this project thus I am taking credit for it". In other words there is probably a stronger charge for misguided clout-chasing than plagiarisms.
