When building a drowned farm, I used a villager to attract the drowned ,but found  that drowned corpse cannot see the villagers and head to the villager. But according to wiki, zombies should be able to find villager through the wall.

After aa little test, I found in 1.13 zombies can still see the villagers through wall, while in 1.14 they can't see villagers through the walls.

If this is a bug,I hope you can fix it as soon as possible.

If this is an update you are planning to make, please add this message in the wiki.
