Probably the easiest thing to do would be to ask yourself if you think it was put in the episode to specifically call attention to a previous episode, or if it could be coincidence or just a placeholder (they need some item to fill a particular background spot, so they re-use a previous design). If it's the latter, it's trivia because we are the ones who think it's significant.
