Thi is actually a MapServer bug that's been around for a while. MapServer doesn't do well when querying in 3857 and the underlying data is in another projection. So we have an option to use the "wgs84Hack" (internal name in the code). This is enabled when the map-source type is set to "mapserver-wfs".
