afaik this is due to reply fallbacks: the @room is actually part of the reply, even though it doesn't look like it.

Interesting! In my opinion I think this is still a bug as an unprivileged user is able to still ping a whole room

unprivileged user is able to still ping a whole room

I don't think they are: In your test case you get a ping because it's a reply to you, not because the reply includes @room
