Running W3C referrer-policy test from [1] and filtering fail cases, I found a case: /referrer-policy/generic/subresource-test/attr-referrer-invalid-value.html Error message : assert_equals: expected \"\" but got \"not-valid-value\ It seems, invalid referrerpolicy should not be reflected. referrerpolicy attribute draft specs is shown in [2], but seems there's no spec mention about that. [1] https://github.com/w3c/web-platform-tests/tree/master/referrer-policy [2] https://w3c.github.io/webappsec-referrer-policy/#referrer-policy-delivery-referrer-attribute

Following [1] invalid referrerPolicy (not referrerpolicy) should be replaced as empty string. [1] https://www.w3.org/TR/html5/infrastructure.html#limited-to-only-known-values.

WIP patch: change referrerPolicy to "limited to only known values" and update test case
