This was speculated in #68, but confirmed in the process of fixing that issue.
What's happening is the jupyterlab-manager is only registering Widgets to the notebook- which works for the cell dashboards, but not for the document editor.
In the Viewer, we had to basically reimplement jupyterlab-manager for the NotebookViewer. I'm hoping we don't have to go that far, and can just apply some function to the editor tracker.
