Bug summary
In astropy/astropy#13209 a potential bug with v3.5.2 has been found wherein a previously working (e.g. in v3.5.1) plot of one of kernel objects now fails. This failure seems to stem from plot no-longer coercing the the kernel object correctly. This seems to be related to the changes in #22141. In any case we have an object with a valid __array__ method which was previously plotting correctly, but now produces a crash.
Code for reproduction
import matplotlib.pyplot as plt
from astropy.convolution import Gaussian1DKernel
gauss_1D_kernel = Gaussian1DKernel(10)
plt.plot(gauss_1D_kernel, drawstyle='steps')Actual outcome
