Unable to create nodes with namespace in MaterialX Graph Editor

[zicher3d]

Tried in MaterialX 1.38.8.

Steps to reproduce: 1 - Unzip and put the attached nodedefs file in your libraries. 2 - Start materiaX Graph Editor 3 - Press Tab to bring up list of nodes 4 - from the "namespace_debug" group, select "nodedef_without_namespace" 5 - A node is created in the work area (correct) 6 - from the same group now select "test:ND_nodedef_with_namespace" 7 - Node is not created

This is a very simplified test file, but it reproduces what I see with all the nodedefs I have that use namespace.
