Bug report

Bug summary

Now when using mpl_toolkits.axes_grid1.inset_locator.zoomed_inset_axis with an inverted axis, the inset box gets placed outside the figure. This was not an issue in the past.

Code for reproduction

This is okay (image B):

from mpl_toolkits.axes_grid1.inset_locator import zoomed_inset_axes, mark_inset
fig = plt.figure()
ax = plt.subplot(111)
ax.plot([1,2,3], [1,2,3])
ax.axis([1,3,1,3])
inset_ax = zoomed_inset_axes(ax, zoom=2.5, loc=4)
inset_ax.axis([1.1, 1.4, 1.1, 1.4])

but this is not (image A):

from mpl_toolkits.axes_grid1.inset_locator import zoomed_inset_axes, mark_inset
fig = plt.figure()
ax = plt.subplot(111)
ax.plot([1,2,3], [1,2,3])
ax.axis([3,1,3,1])
inset_ax = zoomed_inset_axes(ax, zoom=2.5, loc=4)
inset_ax.axis([1.4, 1.1, 1.4, 1.1])

Actual outcome
