I first noticed in a chat message I sent yesterday but now it's more irritatingly present in a comment: something's up with formatting on messages? There's also a question I read today (perhaps elsewhere on the meta) where a user attempted to input italics but it would not let them.
[Link](rpg.stackexchange.com/tour) is correct, yes? Yet when I tried that moments ago it only spat out the code. No link :(
