Hello!
First of all, thanks for this tool it is awesome.

python -m venv .venv
# activate venv 
python -m pip install voila==0.5.5 ipywidgets jupyterlab
voila repro.ipynb

Expected behavior

• Operating System and version: Tested on Windows 10/11 and within a docker container
• Browser and version: Edge, Librewolf, Brave
