What is a standard/recommended way to make this work? What ids and classes does Ipython use?
The Notebook and/or JupyterLab docs could list which DOM IDs are reserved.
https://ipywidgets.readthedocs.io/en/latest/migration_guides.html has info on how to depend on
In quickly reviewing https://github.com/jupyter-widgets/ipywidgets , I wasn’t able to determine whether or how they avoid using reserved DOM IDs.
