Interactivity not working in basic examples

I copied the code from the Build an App example into JupyterLab and ran it. It renders fine and the Bokeh plots are functional (panning, onhover work), but none of the Panel interactivity works – dropdowns and sliders don’t change the Bokeh plots. There doesn’t seem to be anything anomalous in the Chrome developer console and I’ve tried adding .servable() as mentioned in the Develop in a Notebook tutorial.

Here’s a video of what happens to help illustrate.

I’ve been stuck on getting this to work for days. Any help, ideas, or insights would be appreciated.

Hi @apowers

What versions of Jupyterlab, panel and bokeh are you running?
