The ExpansionPanel module doesn't exist anymore (only in v4), it's weird that it's surfacing here. I suspect that Skypack as a caching isolating issue between versions.

Context

I was trying to update our CDN demo that currently uses unpkg with this POC: https://codepen.io/oliviertassinari/pen/gOLOLKM

Notes

Use https://pika.dev/ to find a web-friendly alternative to find another package.

This sentence is semantically wrong.

Hey @oliviertassinari thanks for raising. Yes we do have an issue building the latest alpha release in Skypack. We are working to fix it soon in an upcoming release; are you able to use v4 as a workaround until then?

[oliviertassinari]

I haven't looked into v4, we don't actively maintain it. I will try again later on with v5 :)
