Seaborn appears to set the marker edge width to below 0.1 in matplotlib

When I import seaborn into a python session it appears to reset the default marker edge width to below 0.1 such that non-filled markers e.g. ‘x’ do not show up.

If I do the following:

import numpy as np
import matplotlib.pyplot as plt
plt.plot(np.arange(0, 100), np.random.rand(100), 'x')
plt.show()

I get the expected plot:

However If i import seaborn in the same session:

import numpy as np
import matplotlib.pyplot as plt
import seaborn
plt.plot(np.arange(0, 100), np.random.rand(100), 'x')
plt.show()

I get the following:

Maybe a comment in the documentation would help people solve this issue when it occurs?

Just because something is written in the documentation doesn’t mean everyone is going to read it…
