Steps to reproduce

1. Make a 1 x 1 pillar.
2. Spawn a blaze on top.

Expected result

The blaze wanders off and falls.

Actual result

The blaze does not move.

Impact

At some time in the past it was possible to make blaze farms that would collect blazes by allowing them to wander into holes. For a long time that possibility was blocked by MCPE-45469 / MCPE-45559. With the new blaze behavior those farm designs remain broken.

Code analysis

In the blaze.json entity file, there are two new parameters in the "minecraft:navigation.walk" component. The second of these may be causing blazes to avoid pathing over air.

        "avoid_water": true,
        "avoid_damage_blocks":  true
