ECM Tagging: Tagcloud cannot read hippofacnav:facetnavigation /tags node

The ECM Tagging installation documentation[1] specifies that a 'tags' node should be made under the JCR root which has primary type 'hippofacnav:facetnavigation'. The earlier versions of the plugin used a 'tags' node of primary type 'hippo:facetsearch'. The 'tags' node of type 'hippo:facetsearch' has been replaced with primary type 'hippofacnav:facetnavigation' because this method of searching has proven to more efficient. However, not all functionality in the plugin support the use of a 'tags' node of type 'hippofacnav:facetnavigation' yet. The tag suggestion functionality from within a document works with 'tags' nodes of type 'hippofacnav:facetnavigation' but the tagcloud doesn't. The tagcloud does not display any tag when using this setup.
