Correctly downvoted: 1. guidelines "Please don't complain about tangential annoyances", 2. HN site norms are enforced by downvotes - downvoting is correct by definition
Plus another important guideline is "Please don't comment about the voting on comments". I'm trying to help you moderate yourself - of course the next escalation is for this inane subthread (including my comments) to be flagged.

I think this makes it pretty clear that this guideline wasn't talking about people trying to provide helpful feedback for a developer, letting them know about a strange edge-case (i.e., why should an extension injecting CSS even mess with WebGL content?) that they might want to look into.
We disagree on "tangential annoyances". And that's it from my side.
