It's happening no matter who's Wishlist one views - any games someone has in their Wishlist and you own are labelled as such.
EDIT: And any games on anyone else's Wishlist that you also have on yours have that little heart next to them.
Should I roll my eyes? Or is this supposed to make us come closer?
mrkgnao: You're right. Crawl is OK too. So, for now, it's just Armello and Worlds of Magic. Not going to test them all.

Confirmed, I have those two wishlisted (the little lifeless, grey heart is displayed everywhere else), but they don't show in my Wishlist.
