Layer/source information doesn't show up

[davidbrochart]

When opening the JupyterLite deployment:
https://geojupyter.github.io/jupytergis/lite/lab/index.html?path=france_hiking.jGIS
Nothing appears in the right panel when selecting layers or sources:

simplescreenrecorder-2025-01-10_10.07.05.mp4

It works when opening another jGIS file.

Note: things seem to work when "opening" the file from the file browser, but not when accessing the file directly from a URL with the path URL argument.

This seems to be a duplicate of #232.

I think so too. @davidbrochart please re-open if we're mistaken :)
