There are RTD failures due to a missing ndim in latest PRs, see:

- https://readthedocs.org/projects/astropy/builds/16812180/
I believe this may have to do with the latest version of matplotlib (https://github.com/matplotlib/matplotlib/releases/tag/v3.5.2) interacting poorly with how plots for Box1DKernel, Gaussian1DKernel, RickerWavelet1DKernel, and Trapezoid1DKernel are coded.
Note that a simple attempt at fixing this was tried in #13205; however, I think the fix will be more involved than this.
This is related to matplotlib/matplotlib#22973
