      1 /**
      2 * This test tests values in a popup that is opened with noopener, it does not test them on the page that made the popup
      3 *
      4 * Covers the following cases:
      5 *  - RFP is disabled entirely
      6 *  - RFP is enabled entirely
      7 *  - FPP is enabled entirely
      8 *
      9 *  - (A) RFP is exempted on the maker and popup
     10 *  - (C) RFP is exempted on the maker but not the popup
     11 *  - (E) RFP is not exempted on the maker nor the popup
     12 *  - (G) RFP is not exempted on the maker but is on the popup
