How do you get the tree picker to display for kb_category with Knowledge V3

[Jerry20]

We are just starting the migration from Knowledge V2 to V3, developing our knowledge in Helsinki.   I seem to remember that when you create a knowledge article, assign the knowledgebase and then assign the category, there was a tree picker for the category field.   The dictionary attribute for kb_category has field_decorations=kb_category_reference_lookup.   I'm still seeing the traditional method of displaying categories

There is a Known Error created for PRB658812. You can subscribe to KMv3-style category picker not available on knowledge base article form (KB0596195)   for updates.

Helsinki Patch 2 fixed the problem for us
