Errr no.
If you are doing at that point in time, that there’s no point doing any additional action.
Just display the emote, and let chromium handle it, because it’s too late if you are preloading/caching at the moment of display of the chat line/emote.
I checked to see what I do, I don’t bother preloading Emotes at all, just channel/chat items (chat badges)
