Last time I did this my rothe wandered off with the emote that it couldn't see me and was therefore beginning to wander. Initially I was stealth ed but when the first warning popped up I exited stealth, only to have the same warning pop up again twice before the danged thing wandered off. I expect it's similar to how some npcs will think you're in stealth when you arent, and thusly this post is probably more cautionary than anything. Cheers
