Derpy Oracles face attacking units after focus fire

Multiple streamers, casters, and pro players have commented on an issue with the recent change to the Oracle’s Pulsar Beam attack that have caused it to turn and face an attacking unit after killing another unit, rather than follow the player’s issued commands. It’s been reported previously and according to the following topic, it should be resolved.

However, in recent testing, the behavior still happens. I find it hard to believe that ignoring the user’s issued commands is by design. Is this fix only available in a test patch, or is this issue actually still unresolved? If it’s only available in a test patch, when will it actually go live?
