Game Mechanics: Enchanter pet does not attack enemies while in water

[Lowspudd]

I am aware of this. I was casting from submerged position directly looking at the mob in this instance. Not sinking, because I had stood on the floor of the catacombs in Qeynos. It gave out of sight error because it was straddling the surface plane of the pool. NO MATTER WHAT I cannot cast spells on enemies in water, no matter where I am, their health %, etc.
