`sq.pl.spatial_segment`: wrong cells selected by `groups` parameter

Description

When the groupsparameter is specified in sq.pl.spatial_segment the cells that are plotted are not the cells where adata.obs[color].isin(groups). For example with the mibitof dataset below, when groups = ["Epithelial","Tcell_CD4"] mostly cells on the left side of the image are plotted and these are not the location of these cell types when groups = None.

Minimal reproducible example

import squidpy as sq
import anndata as ad

adata = sq.datasets.mibitof()
sq.pl.spatial_segment(adata,seg_cell_id = "cell_id",library_key  = "library_id",
                      color = "Cluster",library_id = "point23")

sq.pl.spatial_segment(adata,seg_cell_id = "cell_id",library_key  = "library_id",
                      color = "Cluster",library_id = "point23",
                      groups = ["Epithelial","Tcell_CD4"])
