In v3, Product lookups using a geom with an area greater than or equal to one-half the surface of the Earth will return intersections outside of the geom's extent. This due to a documented issue with Oracle Spatial:

We will need to consider how to handle this. In the meantime it is recommended to use geometries smaller than the above limitation as a workaround.
