Summary0033088: BrepFeat_SplitShape does not split shapes after BRepAlgoAPI_Section
Description
BrepFeat_SplitShape does not split shapes into left and right groups after BRepAlgoAPI_Section. Have we misuse the API, or it is a bug?
Steps To Reproducesee the example outlined in
https://www.cnblogs.com/opencascade/p/SplitShape.html

This example works fine if using XY plane, after changed to YZ plane ; from `gp::DZ()` to `gp::DX()`
    BRepAlgoAPI_Section aSection(aCylinder, gp_Pln(gp_Pnt(0.0, 0.0, 15.0), gp::DZ()), Standard_False);

it will not seperate faces into 2 groups: left and right. it seems `aSpliter.Left()` has all the faces, while the `aRightCompound` is empty.
TagsNo tags attached.
