Renewing Mist jumps to disposable pets

Right now, if a Mistweaver casts Renewing Mist and there's a Demonology Warlock or Beast Mastery Hunter nearby when your your Renewing Mist performs it's duplication from Dancing Mists or jumps to another injured target upon healing the current target to full hit points, it can duplicate or jump onto the pet.

This would be fine if it also could not jump onto pets who have a limited duration, such as Wild Imps and Dire Beasts.

Renewing Mist is a core ability that gives us procs of Uplifting Trance. The MW 2pc even buffs it. It's part of MW's raid healing identity. When Renewing Mist jumps to pets and then those pets despawn, stealing and removing Renewing Mist, it super super sucks.

I don't think I have to say that when I hit Thunder Focus Tea right before the pull goes and throw out 4 Renewing Mists courtesy of my Legendary pants-- and watch each one just seemingly fall off the raid, one after the other, green numbers now flowing rapidly from the newly arrived Wild Imps on the Hand of Gul'dan, it super, super super sucks.

This is really annoying and I would appreciate it if it was fixed.
