/**
* This test only tests values in the iframe, it does not test them on the framer
*
* Covers the following cases:
* - RFP is disabled entirely
* - RFP 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
