toposimplify wrongly applied on Topojson data from file

[mattijn]

Observe:

import json
import topojson

# load topojson file into dict
with open("/Users/mattijnvanhoek/Downloads/gm.topo.json", 'r') as f:
    data = json.load(f)
print(data['objects'].keys())

# read as topojson and as geojson
topo_0 = topojson.Topology(data, object_name="gm_features")
topo_1 = topojson.Topology(topo_0.to_geojson(), object_name="out")

topo_0.toposimplify(10).to_gdf().plot()
topo_1.toposimplify(10).to_gdf().plot()

dict_keys(['nl_features', 'gm_features'])

topo_0 is going wrong, where topo_1 is going right
