/**

 * This test only tests values in a blob document that is created by the iframe, it does not test them on the framer

 * Covers the following cases:

 *  - RFP is disabled entirely

 *  - RFP is enabled entirely

 *  - FPP is enabled entirely

 *  - (A) RFP is exempted on the framer and framee and (if needed) on another cross-origin domain

 *  - (B) RFP is exempted on the framer and framee but is not on another (if needed) cross-origin domain

 *  - (C) RFP is exempted on the framer and (if needed) on another cross-origin domain, but not the framee

 *  - (D) RFP is exempted on the framer but not the framee nor another (if needed) cross-origin domain

 *  - (E) RFP is not exempted on the framer nor the framee but (if needed) is exempted on another cross-origin domain

 *  - (F) RFP is not exempted on the framer nor the framee nor another (if needed) cross-origin domain

 *  - (G) RFP is not exempted on the framer but is on the framee and (if needed) on another cross-origin domain

 *  - (H) RFP is not exempted on the framer nor another (if needed) cross-origin domain but is on the framee
