The cause of the bug was computation of incorrect UVBounds in the method ShapeAnalysis::GetFaceUVBounds. In this patch the computation of a box for a 2D curve in the method ShapeAnalysis_Curve::FillBndBox() has been improved taking into account intervals of C2 continuity. Also the fix makes little extension of bounds when making the new surface in ShapeUpgrade_FaceDivide::SplitSurface(), so that all p-curves were fully inside. Test case for issue CR28553
