Refused to execute script from 'path' because its MIME type ('text/html') is not executable

[Ardweaden]

I try to install ipyleaflet inside a Jupyter Notebook, but the map doesn't display. It only renders upon refreshing the page and running it again.

!pip install ipyleaflet
!jupyter nbextension enable --py --sys-prefix ipyleaflet

from ipyleaflet import Map, basemaps
Map(
    center=(0, 0),
    zoom=1,
    scroll_wheel_zoom=True,
    basemap=basemaps.OpenStreetMap.Mapnik,
)

Returns

This is the expected behavior in the current state of ipywidgets's widget manager.

ipyleaflet needs you to load some JavaScript code which only happens upon refresh.

Is there any workaround?
