Description of expected behavior and the observed behavior

hvPlot polygon plot throws an attribute error when used with a tile source

Complete, minimal, self-contained example code that reproduces the issue

import dask.dataframe as dd
import spatialpandas as spd
import hvplot.dask # noqa

square = spd.geometry.Polygon([(0.0, 0), (0, 1), (1, 1), (1, 0)])
sdf = spd.dask.GeoDataFrame({'geometry': spd.GeoSeries([square, square]), 'name': ['A', 'B']})
sddf = dd.from_pandas(sdf, npartitions=2)

sddf.hvplot.polygons(tiles=True)

Also, without dask:

import hvplot.pandas
import spatialpandas as spd

square = spd.geometry.Polygon([(0.0, 0), (0, 1), (1, 1), (1, 0)])
sdf = spd.GeoDataFrame({"geometry": spd.GeoSeries([square, square]), "name": ["A", "B"]})
sdf.hvplot.polygons(tiles=True)
