A bug regarding Jungle Diana.

Not sure if anyone had noticed it or is it intentional, but last time, while I was playing Diana in jungle I realised my passive splash isn't applying the burn dot, from the jungler's item. Everything else applies it just fine, the autoattacks and skills. But the splash damage from autoattack's passive doesn't. Kinda bugs me, as it makes her clearspeed slower.

Should I send it as a ticket?
