Bug summary

I think #21749 wasn't fully fixed. mpl_toolkits.axes_grid1.inset_locator.inset_axes still appears to be affected. This still throws in v3.5.1:

Code for reproduction

import matplotlib
import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1.inset_locator import inset_axes


matplotlib.__version__
# > '3.5.1'

fig, ax = plt.subplots(1, 1)
pts = ax.scatter([0, 1], [0, 1], c=[1, 5])

cax = inset_axes(ax, width="3%", height="70%")
plt.colorbar(pts, cax=cax)

plt.tight_layout()

Actual outcome

AttributeError: 'AnchoredSizeLocator' object has no attribute 'get_subplotspec'

Expected outcome

No error
