Research direction

Start by tracing _MeshIndexSet indexing and compare the existing node-connectivity path with face_face_connectivity. Confirm how indexing edges and faces should construct non-node connectivities, then verify that the resulting connectivity matches the expected indexed mesh behavior.

Written by the indexing model from the issue text.

Description

E.g. face_face_connectivity

This a pure oversight. Will need different code to what we have currently done for nodes when indexing edges/faces.
