[Gameplay] About "Dealing (physical) damage" with pets

I tested AD malzahar. Before ver5.22 , his pet "Voidling" 's basic attack procs 's passive "Dealing physical damage to an enemy champion Cleaves them, reducing their armor by 5% for 6 seconds" AND 's passive "Bloodlust: Dealing physical damage to champions heals for 15% of the damage dealt.". But now, voidling's damage procs ONLY 's passive. and 's passive "Dealing physical damage (to champions) heals for..." is NOT working. (I didn't test about , but maybe not working either.)

I hope this is a bug... but If Riot says this is specification, then Riot should change the explanation, or add clear sentences.

Sorry about my poor English.
