const feature = this.newFeature(multiPolygonGeoJSON )
this.addFeature(feature )
After adding this MultiPolygon feature to the map, I drew a feature and used the difference tool between this feature and the MultiPolygon feature. The expected result should be a feature of type MultiPolygon, but instead, the returned feature is of type Polygon, and it has one less line compared to the MultiPolygon feature.
