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

importmatplotlib.pyplotaspltfig,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

TrueFalse# and the plot is **not** inverted

Expected outcome

TrueTrue# and an inverted plot
