SimpleType extension across mixed static/dynamic namespaces is broken

I have a statically registered namespace "http://www.example.com/substitutionEV" with a simpleType named UuidType with a pattern facet. I also have a dynamically registered namespace "http://www.example.com/substitutionEV2" with a simpleType named Uuid2Type which is a restriction of UuidType. When I invoke uuid2Type.getBaseTypes(), the parent UuidType is not returned. I have included a sample test below.
