CSP: manifest-src

The HTTP Content-Security-Policy: manifest-src directive specifies which manifest can be applied to the resource.

Content-Security-Policy: manifest-src <source>;
Content-Security-Policy: manifest-src <source> <source>;

Sources

Note that this same set of values can be used in all fetch directives (and a number of other directives).
