Unable to disable autoscaling in pyplot.plot

Bug summary

Arguments to disable autoscaling are not working, so despite e.g. scalex=False the horizontal axis is re-scaled.

Code for reproduction

import matplotlib.pyplot as plt

plt.plot([0, 2], [0, 2], '-')
plt.plot([0, 10], [1, 1], '-', scalex=False)

Actual outcome

Output in-line in jupyter notebook:

Expected outcome

Expected autoscaling only for the first call, so the xscale is just a bit padded from [0, 2]. This works as expected in matplotlib==3.1.3:
