Wacky Hurtbox on DeGrey's jS

I had this happen to me in a match, and I’m not really sure what to make of it. It seems absurd that Jaina’s Red Dragon passes directly through DeGrey’s Final Arbiter without connecting. Would it be possible to tweak? I can’t make any sense as to why DeGrey wins this interaction outright.

While its less likely, this can also happen with Jaina facing towards DeGrey

Wao, that just looks awful

Looks fine to me. It’s not easy to beat The Ultimate Punch of Justice™; you probably need some kind of high priority attack. Rooks jS works.
