Can't create a geometry from a multipolygon relations

[ldalzovo]

I noticed that I can correctly access objects of type 'area' extending osmium.SimpleHandler and create the geometry object using create_multipolygon(). In this case is then possible to know if the area comes from 'way' or 'relation' using from_way() and both work using a specific pbf extraction of the city of Rome.
Nevertheless, not all the multipolygon relations are available as area unfortunatelly, and I can access them as relation, but I can't create a geometry, as in the case of https://www.openstreetmap.org/relation/11153 or https://www.openstreetmap.org/relation/8655602: it looks valid and therefore it should be possible to get a geometry. I am also sure that all the nodes and ways are in the pbf, so this cannot be the issue here.
Do you have any idea how I can create a valid geometry in these cases? Thank you!

Works for me. If I download the full relation 11153:

wget -o test.osm https://www.openstreetmap.org/api/0.6/relation/11153/full

and then run in with this sample program:

import osmium as o
import sys

wktfab = o.geom.WKTFactory()

class Handler(o.SimpleHandler):
    def area(self, a):
        print("Found area", "way" if a.from_way() else "relation", a.orig_id())
        geom = wktfab.create_multipolygon(a)
        print(geom)

if __name__ == '__main__':
    Handler().apply_file(sys.argv[1])

I get:
