Ravagers are able to attack player through blocks from a distance of at least 3 blocks away

During the villager raid I was trying to hit a ravager but I noticed that it was able to do about 8 health points of damage through nontransparent blocks like dirt, grass, and stone. It was able to hit me through fences and fence gates. I have railroads going around my village too so I noticed that the ravager would get stuck on the railroad by constantly spinning around on them.
