What is the current behaviour?
sw.js is loaded from a CDN if a CDN is set in the webpack publicPath. This is forbidden:
Failed to register a ServiceWorker: The origin of the provided scriptURL ('https://yourcdn.net') does not match the current origin ('https://yourapp.com').

If the current behaviour is a bug, please provide the steps to reproduce.
Add the following snippet to preact.config.js:

config.output.publicPath = '//youcdn.net/';

It seems this was introduced in #323

What is the expected behaviour?
sw.js must be loaded from the base domain. See w3c/ServiceWorker#940
