extrudeMesh extrudes side faces into faceZone

Functionality to add/problem to solve

extrudeMesh when creating 'side' faces (i.e. extruding edges into faces) takes their patch information from existing 'side' faces but any zone information from the extruded face. This seems inconsistent.

In below pic there was a single face in between two cells being extruded. After extrusion all the side faces are in the face zone as well

Target audience

extrudeMesh users

Proposal

Take zone information from the same face we get the patch information from?
