follow_range attribute not working for piglins

MC-183636 says this bug is fixed, but I don't think so.

By using commands like the one below, you can create piglins with a very wide detection range. However, they will not notice you even if you attack them from a distance.

/summon piglin ~ ~ ~ {PersistenceRequired:1b,IsImmuneToZombification:1b,attributes:[{id:"minecraft:follow_range",base:128}]}

This doesn't happen with other mobs, they just chase you from afar. Could this be because Piglins have Brains?
