Apologies, wasn't trying to be snarky. If you are configured to allow resources to load from anywhere, the CSS can load a resource from anywhere, not just the location it originated from. These kinds of configurations are increasingly less the default, however, so depending your specific setup, you may find that some origin policies are in place by default. This is entirely dependent on your chain, however, including browser settings.

Yes, of course - but what is the default if you don't have a CSP? I guess I will have to do the experiment.
