Bug report

Bug summary

When plotting on a log axis that has been inverted, the inverting is overwritten.

This happens for "log" and "logit" scales but not for "linear" or "symlog", which both work as expected.

Code for reproduction

import matplotlib.pyplot as plt


fig, ax = plt.subplots()
ax.set_yscale('log')  # or 'logit'
ax.yaxis.set_inverted(True)

print(ax.yaxis.get_inverted())
ax.plot(range(50), range(50))
print(ax.yaxis.get_inverted())

Actual outcome

True
False
# and the plot is **not** inverted

Expected outcome

True
True
# and an inverted plot
