Damage mechanic bypasses OnDamaged aura conditions (damageCause/damageTag not respected)

damageCause and damageTag Conditions in OnDamaged Auras don't work with damage mechanic (though they seem to work fine on mobs with ~OnDamaged Trigger). For example, when I use /mm t cast withercloak followed by /mm t cast WitherDamage, the damage isn't canceled and the run the onHit. However, if I use /minecraft:damage @p 100 minecraft:wither, the WitherCloak aura cancels the damage properly. So I think MythicMobs’ Damage mechanic might be bugged

WitherDamageCommand:  
  Skills:
  - command{c="minecraft:damage <target.name> 100 minecraft:wither"} @Self

WitherDamage:  
  Skills:
  - damage{a="100";dc=WITHER} @Self      
  
Withercloak:  
  Skills:
  - onDamaged{auraName=Withercloak;d=100;cE=true;oH=Withercloak-blocked} @Self
Withercloak-blocked:
  Conditions:        
  - damagecause{cause=WITHER} true
  Skills:
  - message{m="wither damage canceled"} @Self

Ps. I'm pretty sure I used them correctly, since the aura work with minecraft:damage command. I tried TriggerConditions too, it also doesn't care about mythicmobs damage's cause.
