Rise slides not rendered with ipywidgets>=8.0.0 #119
Description
Description
With ipywidgets>=8.0.0, when clicking the rise button in jupyter lab, the tab appears but the content stays empty.
I noticed that with ipywidgets==7.8.5 it works fine.
Reproduce
Ensure the latest ipywidgets is installed and launch jupyterlab. Open a notebook and click the rise button.
Expected behavior
Should render the slides.
Context
python 3.12.9
