Verification builds: Release 924386 - 1.5.0.4 BETA
Summary: With the added "minecraft:behavior.owner_hurt_target" a tamed mob is supposed to attack the same things you attack. This does not work on the following mobs: Blaze, Cave Spider, Magma Cube, Slime, Spider, Guardian, Elder Guardian

Repro Steps:

1. Download the 'super behavior bug test time' (tm) map from Greg on Slack

Observed Results:

1. Your tamed mob just stares at you and doesn't care about your troubles

Expected Results:
