alpha value of markeredgecolor is overwritten by markerfacecolor

[hitzg]

When setting both the markeredgecolor and the markerfacecolor as a rgba tuple, the transparency of both seems to be set to the one of markerfacecolor. Could this be a bug in matplotlib or am I making a mistake?

Minimal-ish example:

import matplotlib.pyplot as plt

# plot markers with varying alpha values for edge and face colors
alpha_faces = [1.0, 0.3, 0.7, 0.3]
alpha_edges = [1.0, 0.3, 0.3, 1.0]
for n, (af, ae) in enumerate(zip(alpha_faces, alpha_edges)):
    plt.plot(n, 0, ms=20, mew=5, marker='s',  mfc=(1,0,0,af), mec=(0,0,1,ae))
    plt.text(n, 0.01, "$\\alpha$ edge: {}\n$\\alpha$ face {}".format(ae, af),
            va='bottom', ha='center')

# a black line to make the transparency clearer
plt.axhline(0, color='k', lw=3, zorder=0)

plt.xlim(-0.5, n+0.5)
plt.show()

Result:

Versions: Ubuntu 12.04, python 2.7.3, matplotlib 1.4.3

I also posted this as a question on SO.
