Mobs that can burn do not avoid campfire

Mobs that can burn should avoid campfires, but they do not do this and go straight through them. In this regard, taiga villages can self-destruct, as villagers do not avoid campfires and burn down. 

Instructions for reproducing:

1. Create a 7x7 square of campfires, and then create a safe exit from this square.

2. Create a villager and a zombie in this square.

 

Expected results: villager will try to escape from zombies through a safe exit from this square.

The observed result: villager simply runs through campfire and catches fire. And after him, too, a zombie runs right through campfire
