RuntimeError: adjustable='datalim' is not allowed when both axes are shared. #11416
Description
Bug report
Bug summary
Matplotlib 2.2.2 fails to plot the figure described below. The code works with Matplotlib 2.0.2.
The issue seems to be the combination of sharex=True, sharey=True and axis('equal').
Code for reproduction
import matplotlib.pyplot as plt
import numpy as np
nrows = 3
ncols = 2
fig, axes = plt.subplots(ncols=ncols, nrows=nrows, sharex=True, sharey=True)
n = 20
np.random.seed(1234)
data = np.random.uniform(size=(nrows, ncols, n, n))
for i in range(nrows):
for j in range(ncols):
ax = axes[i, j]
ax.imshow(data[i, j])
ax.axis("equal")
plt.show()Actual outcome
With Matplotlib 2.2.2, the figure is not drawn and the following exception is raised:

Expected outcome
Drawn figure, no error, as with Matplotlib 2.0.2
