AFAIU, this is not a bug in OGR, but OGR GeoJSON drivers works with
GeoJSON format
whereas JSON produced by ESRI is a different format, not GeoJSON.

Can you?
There is no geometry of multipolygon specified.
AFAIU, for multipolygon ESRI REST produces a hybrid: a Polygon that
contains detached rings
(or rings not in other rings, so they are not holes) and that is
interpreted as multipolygon.

Fun.
