minecraft:delayed_attack mobs CAN NOT start an attck above ANY half bricks.

these are code of a melee attack mob with component of delayed_attack:

{{"minecraft:attack": { "damage": 9 }, "minecraft:behavior.delayed_attack": { "priority": 2, "speed_multiplier": 1.2, "track_target": true, "hit_delay_pct": 0.59, "attack_duration": 1.12, "reach_multiplier": 4.0 }}}

these mobs can not start an attck above all half bricks.

I Tried other delayed_attack mobs, they have the same problem.
