This document has the header Cross-Origin-Embedder-Policy: require-corp.
Cross-Origin Embedder Policy Editor's draft: https://mikewest.github.io/corpp/
This test is retrieving same-origin and cross-origin resources from the
CacheStorage. The resources are generated from the ServiceWorker or from the
network with the header Cross-Origin-Resource-Policy being one of:
- 'same-origin'
- 'cross-origin'
- <undefined>
