every 200ms flush shifted all sliver indices (reverse list), and the per-row ObjectKeys without findChildIndexCallback made the framework deactivate and re-inflate every built row instead of moving it. add the callback so elements move, and cache ChatMessage widget instances per message (Expando) so unchanged rows skip build() entirely via the identical-widget short-circuit. IRCMessage.renderRevision invalidates rows the CLEARCHAT/CLEARMSG handlers mutate in place. also decode emotes/badges at display size (memCacheHeight = logical size x devicePixelRatio) instead of the CDN's 3x-4x intrinsic size: several-fold less image memory and raster cost, animation preserved (ResizeImage applies the target size to the whole codec).
