"WebbA Polygon is allowed to have self-intersections, this is conform with the GeoJSON specification. However, it frequently causes issues in downstream applications thus is often rejected by APIs and tools. A common approach for removing the self-intersections is applying a zero-buffer operation (e.g. .buffer(0) in shapely). " - Shapely multilinestring intersection
