Killing a mob in one hit using a weapon with Fire Aspect doesn't make it drop cooked meat

Easily testable across all game modes. If you one-hit a passive mob that drops meat with a bow shot, using a bow that has Flame on it, it will drop cooked meat. If you one-hit the same kind of mob with a sword, using a sword that has Fire Aspect on it (You'll probably need sharpness as well, diamond sword alone doesn't always one-hit) then the mob doesn't drop cooked meat.
