// we normally expect _6_ violations (6 test cases that cause blocks), but many
// of the cases cause violations due to the // origin of the test harness (same
// as 'a'). When the violation is cross-origin, the URI passed to the observers
// case or if it is the test harness frame (also origin 'a').
// As a result, we'll get an extra violation for the following cases:
// ab_block "frame-ancestors 'none'" (outer frame and test harness)
// aba2_block "frame-ancestors b" (outer frame and test harness)
// abb2_block "frame-ancestors b" (outer frame and test harness)
//
// and while we can detect the test harness check for this one case since
// the violations are not cross-origin and we get the URI:
// aba2_block "frame-ancestors b" (outer frame and test harness)
//
// we can't for these other ones:
// ab_block "frame-ancestors 'none'" (outer frame and test harness)
// abb2_block "frame-ancestors b" (outer frame and test harness)
