Indeed, this never made any sense to me. I always use the preview on glam items, and the earrings are basically invisible.
I like this events. They give me a good reason to dust off some my less played characters to add a new mount to their list. And since I do not participate in any form of end game content, my main also always finds something interesting on the list.
If this makes me a sprout in your book - well, then I'm a sprout. Is there a way to reactivate that symbol on my character?
