IfcProxy missing in geometry loading

[pbbr]

We've recognized that IfcProxy geometries are missing in flatMashes after the geometry loading with web-ifc:
const flatMeshes = ctx.ifcAPI.LoadAllGeometry(ctx.modelID);

When the same ifc model is loaded in the web-ifc-example viewer (https://tomvandig.github.io/web-ifc/examples/viewer/index.html), all IfcProxy geometries are there. Futhermore, if we rename the "IfcProxy" objects with e.g. "IfcWall", the geometries are also loading.

@xeolabs Do you have any idea how to solve this?
