Link IFC - Incorrect model IfcShapeRepresentation(MappedRepresentation)

[klqa_test]

Hello,

There is a problem when link IFC in Revit 2020 with IfcShapeRepresentation using mapped representation type.

Based on my debug with two mapped representation IfcProduct:

IfcFurnishingElement ('Table') - with 4 IfcMappedItem

IfcFurnishingElement('TwoBox') - with 2 IfcMappedItem

The sequence of the IfcProduct matters when link IFC in Revit 2020.

In the IFC file, if the Table is first IfcProduct, and TwoBox is later, link IFC shows correct model - TableAndTwoBox.ifc

In the IFC file, if the TwoBox is first IfcProduct, and Table is later, link IFC shows incorrect model - TwoBoxAndTable.ifc

Both IFC files looks correct with open IFC in Revit2020, and looks correct to load in other IFC software such as BimVision and Solibri.
