Orbital onHit meta-skill does not trigger

Using

    - orbital{
      i=1;d=50;
      ox=0;oy=1.5;oz=0;
      rx=0;ry=0;rz=0;
      vx=0;vy=0.5;vz=0;
      p=64;
      hp=true;hnp=true;hs=true;se=true;
      c=1;
      hR=0.5;
      r=0.8;
      onTick=[
        - particles{p=flame;a=0;y=-0.3;delay=3} @origin
        - modifyProjectile{trait=RADIUS;action=MULTIPLY;value=1.03}
        ];
      onHit=[
        - message{m="hit"} @self
        - message{m="hit"} @server
        ];
      onEnd=[
        - sound{s=entity.dolphin.jump;p=2} @origin
        - message{m="end"} @self
        - message{m="end"} @server
        ];
      } @ring{r=4;p=3}

onHit does not trigger upon hitting an enenmy. The orbital continues to persist after phasing through a mob and not showing any hit messages in chat. This could be related to the enemy that should have been hit not being the initial target defined in the skill (ring in this case), but unconfirmed.
