2018-03-12 Custom javascript does not in jupyter labΒΆ

I was surprised to see that the same code is working with a notebook server and not in Jupyter Lab. Here is the reason : Jupyter Lab extension to support JavaScript output which are disabled in JupyterLab, how to restore script tags in trusted HTML output. I did not find any easy to enable javascript back. A couple of direction: javascriptRendererExtension.ts, jupyter-renderers, vdom. Maybe, it will get easier.
