A pickled representation of the graphics object can be found here. Basically the problem appears to be somehow SageMath detect that there is a pole or something at 0 and draw a vertical dotted line there (which is the primitive g[6]).

(reproduce with G = Graphics(); G.add_primitive(o[6]); G.axes(False); G)
