modDamageType not work in onDamaged aura

BugReport1:
  Skills:
  - onDamaged{
      auraName=br1;
      d=300;
      rd=false;
      i=1;
      bt=true;
      damagetype=ENTITY_ATTACK;
      oD=[
        - m{m="It's EntityAttack!!"} @Self
      ]} @Self

As intended, this aura skill should only activate upon receiving ENTITY_ATTACK damage, but in reality, it triggers upon any form of damage.
