0.5.8 breaks ipywidgets display on "windows server 2019" #1512
Description
Description
on a windows server 2019 computer I have the following issue:
using pip install voila==0.5.8 ipywidgets jupyterlab
a simple notebook test.ipynb with a single following cell;
import ipywidgets
ipywidgets.IntSlider(value=2, min=1, max=10)just displays text
while running in jupyter-lab it works
Note that downgrading to voila==0.5.7 the voila rendering is fine, so the issue is really recent (again, for windows server 2019)
Reproduce
- create a fresh environment (py3.12.4)
- activate the environment
- pip install voila==0.5.8 ipywidgets jupyterlab
- run voila --debug test.ipynb
- in the browser we only see a textual version of the widget.
Expected behavior
expected to see the slider widget, not a text with the slider creation code
Context
- voila version 0.5.8
- Operating System and version: Windows Server 2019 Standard (ver 1809)
- Browser and version: Chrome Version 131.0.6778.109 (Official Build) (64-bit)
