Switching across channels, even across different servers, carries a message's reaction icons from the previous channel into a message from the current channel.
So upon switching channels you get a message with the right emote and number of reactions (the vanilla bit) but wrong user icons. Wrong profile pictures (from the previous channel/server) and wrong amount of them. The reaction list is unaffected.
