`pl.show()` leading to `ValueError` due to mismatch between number of axes and number of panels

Report

Blocking a release. To reproduce please run notebook_spatial_query.ipynb from spaitaldata-notebooks.

Some notebooks started throwing some ValueError due to a mismatch between the number of axes and the number of panels in the plot. If possible, I would try to be backward compatible.

Again, session_info2 seems to be uninformative. Please let me know if you can't reproduce and I will dig deeper.

This was occurring in the notebooks visium and spatial_query. As a workaround I pass coordinate_systems explicitly in pl.show() (see scverse/spatialdata-notebooks#169). But this at times is very verbose, so I advocate for a fix please.
