na_color stopped working in render_shapes()

[LucaMarconato]

Sorry not making a MWE because I don't want to break the flow in fixing another bug.

import matplotlib.pyplot as plt

blob = sd.datasets.blobs()

# otherwise pre-commits will remove the "unused" import
_ = spatialdata_plot

ax = plt.gca()
blob.pl.render_shapes(element="blobs_shapes", na_color=(1.0, 0.7, 0.7, 0.5)).pl.show(ax=ax)
plt.show()
