It's generally (although not always!) a requirement of CSRF that the
user has already logged in. So there won't be any new notification
window popping up.
It will make it harder for the attacker to stealthily attack multiple
targets without someone noticing, though.
Like Basic Authentication (which is ugly for the end-user, but browsers
can defend slightly better against attacks over it), this is one of the
cases where a little bit of user friction helps reduce attacks.
It's an open question as to whether end users pay attention to security
pop-ups at all. :)
