Pets/auto-attackers drop aggro on Power Word: Shield targets

Tested on Covenant M0 (21.14.85)

A pet will stop attacking the target if there is an absorb effect on it. This absorb shield buff can be used after a pet starts attacking to make it drop aggro in 1-4 attacks usually. Pet attacking in melee or casting does not matter. I have not tested with a hunter yet.

To reproduce, have 1 horde and 1 alliance character or duel. Have one character be a priest and another be a warlock. Have the pet attack the priest in melee or with a spell. Now on the priest, cast Power Word: Shield. The pet will stop attacking within 4 attacks usually.

The pet will sometimes keep attacking normally if you send it to attack again while the shield buff is still active. But if the priest drops the buffs and adds them again the pet will once more drop aggro.
