Advanced Blending mode at 0% opacity punches through all layers below if the layer matches compsize and framing

I have a comp size solid that I have a layer style stroke on and. when I change the Advanced Blending it punches through all layers below as if it was on Stencil Alpha. And oddly enough trying Stencil Alpha or Silhouette Alpha changes nothing. But if I move the layer 1 pixel it operates as expected. Also if I draw a mask on it. So my workaround right now is to have a mask that is bigger than the layer.
