This is unnecessary since the first test cases tests the same.

 
   for (const auto& test : cases) {
-    std::vector<MediaListDirective*> policiesB;
+    HeapVector<Member<MediaListDirective>> policiesB;
     for (const auto& policy : test.policiesB) {

+      policiesB.append(
           new MediaListDirective("plugin-types", policy, csp.get()));
     }
 
     EXPECT_EQ(A.subsumes(policiesB), test.subsumed);
     EXPECT_EQ(emptyA.subsumes(policiesB), test.subsumedByEmptyA);
