The emoji picker used bottom:100% and was clipped by the message list's overflow when reacting to a message near the top (and could spill past the right edge). Open it downward + edge-anchored (right for others' messages, left for my own) with width:max-content so all emojis stay visible. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
