<!--
This wpt should run on an origin different from https://www1.web-platform.test:8444/,
from where cross-orign WebBundles are served.
This test uses a cross-origin WebBundle,
which is served with an Access-Control-Allow-Origin response header.
`corp.wbn` includes three subresources:
a. `no-corp.js`, which doesn't include a Cross-Origin-Resource-Policy response header.
b. `corp-same-origin.js`, which includes a Cross-Origin-Resource-Policy: same-origin response header.
c. `corp-cross-origin.js`, which includes a Cross-Origin-Resource-Policy: cross-origin response header.
