Panel Leafmap: 404 GET /static/extensions/ipywidgets_bokeh/3dfd3127e3794acab459.woff2

I'm trying to get leafmap working with Panel similarly to Solara-Leafmap.

A lot of features work. But when in the logs of the server I see

import leafmap

import panel as pn

pn.extension("ipywidgets")

widget = leafmap.Map()

layout = pn.Column(
    widget,
).servable()

I have the same issue. My installation of ipywidgets_bokeh 1.6.0 was done through pip in a docker container. The folder ENV/lib/python3.11/site-packages/ipywidgets_bokeh/dist/ does not contain any font files. Neither do the wheels on pypi. I think the issue is simply that MANIFEST.in does not include the font files!

In fact, I'm not sure I see why any files generated in the dist folder should be excluded, maybe the easy fix is simply to recursive-include all files?
