This patch does more than adds a CSP check. It also adds a mixed content check. We also need to add a nosniff check and the Fetch spec also has a MIME type check. Do you plan to follow up to add the other checks?

Please add test(s) for mixed content.

no sniff and mime type checks are done at the response processing level right now.
We could do some refactoring in the future to better match the spec but this is not needed right now.

I'll remove the check for now and will investigate potential mixed content issues as a follow-up.
