plt.axvspan does not work with lmplot

I am on seaborn 0.13.2.

d = sns.load_dataset('penguins')
g = sns.lmplot(data=d, x='bill_length_mm', y='bill_depth_mm', row='sex', col='species')
g.map(plt.axvspan, xmin=30, xmax=50, color='green', alpha=0.2)

raises an AttributeError. However, using the same map method, the below code works:

d = sns.load_dataset('fmri')
g = sns.relplot(data=d, col='region', x='timepoint', y='signal', kind='line', row='event')
g.map(plt.axvspan, xmin=0, xmax=5, color='green', alpha=0.2)

The full error message is below.
