[bug?] MakeBoundaryMesh with dimension=SMESH.BND_1DFROM2D not working on internal faces if they were previously generated

[otaolafranc]

Hello,
I found a bug in regards to makeBoundaryMesh elements, with MakeBoundaryOfEachElement we can make 2D elements (faces) for all 3D elements of the mesh (ie., internal faces). but if once want to make the internal edges (edges on each of the internal faces) this does not work it will only generate the edges on the external faces. not sure if this is deliberate or missing feature or simply a bug.
regards,
