Specification
https://html.spec.whatwg.org/#initialize-worker-policy-container
https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Security-Policy#csp_in_workers

Summary

Dedicated workers should be governed by the Content Security Policy
delivered in their script response headers. Chrome incorrectly used to
instead apply the Content Security Policy of the owner document. We would
like to change chrome's behaviour to adhere to what is specified.


For background, see the discussion on the github issue where this was
agreed: https://github.com/w3c/webappsec-csp/issues/336
