Camoflage reveal indicator not showing vs kogmaw passive

Currently when kogmaw is in his passive detonation form and enters camoflage range of another champion it does not show that champion that they are being revealed.

Seen with twitch camoflage vs kogmaw passive, kogmaw enters twitch's radius but it does not show the "!" exclamation point above twitch notifying him he is being revealed nor does it show the "oracle eye" icon above him when kogmaw gets close in passive form.

May effect other attack after death passives like karthus' death defied or other camoflage effects aswell.
