My question Why are some emoji B&W and others too big? has been closed as opinion-based. I don't understand the reasoning. This question asks what technical issue is leading to a reproducible visual glitch. The comments and answer address that question, and provide a practical workaround.
I don't think the question and answer were brilliantly worded, so I'm keen to clean them up anyway. Can someone point out the opinion-based or opinion-begging parts so I can address them specifically?
