Bug report

As discussed w@ImportanceOfBeingErnest#10148

All API sources seem to have.. include:: matplotlib.patches.Wedge.examples including many that don't have any examples shown (i.e.https://matplotlib.org/_sources/api/_as_gen/matplotlib.axes.Axes.plot.rst.txt)

These allow examples that are in the gallery to be linked to the API so users can easily see how to use the method (i.e.https://matplotlib.org/api/_as_gen/matplotlib.patches.Wedge.html#examples-using-matplotlib-patches-wedge)

Not sure howmatplotlib.patches.Wedge.examples gets generated. There is one generated formatplotlib.axes.Axes.plot.examples but it is empty. I somewhat suspect the issue is the extra level of nesting. Either we should find the config option or open an issue at Sphinx Gallery to get the extra level traversed?
