[fixed/closed]Cauldron Haze or persist mechanism

[Aswan jaguar]

Describe the Bug:
Cauldron Haze has to mess up with other cards persist ability.If I remember correctly I had played Cauldron Haze on my Deathbringer Liege and the persist ability didn't trigger as Deathbringer Liege didn't die.On my next turn or the turn after I cast a black spell - Ebon Dragon, Deathbringer Liege ability triggers and I target AI's Glen Elandra Archmage and instead of persist returning Glen Elandra Archmage it put into AI's battlefield a Deathbringer Liege with a -1/-1 from persist.
