Steps to reproduce

1. Load Not Attacking.mcworld . It contains villagers and zombies trapped next to each other, as well as a trapped zombie and vindicator that the player can walk up to.
2. Observe the zombies and villagers. Walk up to the zombie and vindicator where there are openings.

Expected results

The zombies attack the villagers. The zombie and vindicator attack you when you stand on the trapdoor in front of them.

Observed results

None of the mobs attack.

Since this update when I try and zombify a villager the zombies won't react when they are on another height level. See attached image which was taken in survival where you see that two zombies both won't attack the villager while it is not on the same height level. This bug breaks all villager farms which use zombification to get better prices from the villagers.
