Embedding widgets into static HTML files from Jupyter Notebook and Lab

[cornhundred]

The latest un-released nbconvert (after pull request #792) is able to generate HTML files with embedded widgets when nbconvert is run in the terminal.

Is there a timetable for releasing a new version of nbconvert that works from the Jupyter Notebook or Jupyter Lab? Currently saving an HTML with widgets from the Jupyter notebook does not produce notebooks with correctly rendered widgets. I raised a similar issue here.

Comparing the html exported from the notebook (v5.6.0) with the output of using nbconvert directly (v5.4.0 of course) reveals the source of the problem:

<     var widgetRendererSrc = '@jupyter-widgets/html-manager@*/dist/embed-amd.js';
---
>     var widgetRendererSrc = 'https://unpkg.com/@jupyter-widgets/html-manager@*/dist/embed-amd.js';

<         widgetRendererSrc = 'jupyter-js-widgets@*/dist/embed.js';
---
>         widgetRendererSrc = 'https://unpkg.com/jupyter-js-widgets@*/dist/embed.js';

So it appears that the notebook does not correctly set the prefix of the js libraries.
