Steps to reproduce the problem:
1. In Apache's .htaccess set either:

Header always set Referrer-Policy "strict-origin-when-cross-origin"

or

Header always set Referrer-Policy "strict-origin"

2. Create an simple html file on the server and open it in the browser

What is the expected behavior?
The browser should recognize and respect the 'strict-origin' and 'strict-origin-when-cross-origin' referrer policies as outlined in the standard:

https://www.w3.org/TR/referrer-policy/#referrer-policy-strict-origin-when-cross-origin

What went wrong?
In console a red message appears:
---
Failed to set referrer policy: The value 'strict-origin-when-cross-origin' is not one of 'no-referrer', 'no-referrer-when-downgrade', 'origin', 'origin-when-cross-origin', or 'unsafe-url'. The referrer policy has been left unchanged.
---

IOW the set of recognized values does not include the full enum of values:

https://www.w3.org/TR/referrer-policy/#enumdef-referrerpolicy

Did this work before? N/A 

Chrome version: 58.0.3029.96  Channel: stable
OS Version: openSUSE Leap 42.2
Flash Version: Shockwave Flash 25.0 r0

Other policies like 'no-referrer' work as expected but not 'strict-origin-when-cross-origin' and 'strict-origin'
