Bug report

Bug summary

A simple 3D scatter plot is not working on jupyter notebook when %matplotlib notebook is enabled. However, it is working for %matplotlib inline

An extremely large, blank window appears that spans beyond the page.

Code for reproduction

%matplotlib notebook

import numpy as np
import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D

A = np.random.random((100,3))
fig = plt.figure()
ax = Axes3D(fig)
ax.scatter(A[:,0], A[:,1], A[:,2])
plt.show()

Actual outcome

Expected outcome
