The electron diffraction isn't caused by currents within the material, but by interaction between the electron's field and the currents induced in the superconducting electrons of the slits. There isn't enough energy in the passing electron to create a current flow in either conductor or insulator, but the surface electrons in any slit material will interact with the fields of the passing electron to create the observed diffraction pattern.
