Bug report

Markers disappear if I use markerfacecolor='None', when saving as eps file. if I save as png file, they are correctly displayed.
Note that markeredgewidth is correctly set to a non zero value and markeredgecolor is correctly set to a color. As I said, the figure is correctly produced when saved as png, so it should really work similarly for eps figure, but it doesn't.

Code for reproduction

I'm too lazy for a complete reproducible example. But here are the relevant lines.

axe.plot(x, y, linestyle = '-', linewidth=0.5, marker = 's', markeredgewidth = 0.5, label='something', c
    lip_on= False, markersize = '3',markerfacecolor='None', markeredgecolor='green', color='green')

plt.savefig('another_name_come_on_not_this_again.png', format='png', dpi=400)
plt.savefig('another_name_come_on_not_this_again.eps', format='eps', dpi=400)

Only the line is displayed. No marker.

Expected outcome

As said above, the edges of the makers should be displayed, as in the case when the picture is saved as png. But they aren't.
