difference operation looses polygon

In Boost 1.86 an inner loop vanishes during the difference operation in the program below. In order to reproduce the error, I have to serialize it with 18 significant digits, 15 is not enough. This may therefore be related to issue 1241.

```

int main(int, char**)

using Point2D = boost::geometry::model::d2::point_xy;
using PolygonCCW = boost::geometry::model::polygon;
using MultiPolygonCCW = boost::geometry::model::multi_polygon;
