Wardens Avoid Lava Despite Being Immune To It

Wardens are immune to lava, but attempt to avoid it even when a target is submerged in lava. This isn't in parity with Java and defeats the point of it being immune to lava.

 

Steps to recreate:

1. Make a lava pool and summon a mob/player inside of it. Make sure the mob or player is resistant to fire or immune to damage.
2. Spawn a warden outside of the lava.
3. Wait for enough vibrations to be sent out from the mob or player to cause anger.
4. Observe the warden fail to get to the player/mob.
