+ * This test only tests values in a data document that is opened in a popup with noopener
+ * Because there is no interaction with a third party domain, there's a lot fewer tests
+ *
+ * Covers the following cases:
+ *  - RFP is disabled entirely
+ *  - RFP is enabled entirely
+ *  - FPP is enabled entirely
+
+ *
+ *  - (A) RFP is exempted on the popup maker
+ *  - (E) RFP is not exempted on the popup maker
