/**
 * Helper script for mixed content testing. It opens a new top-level window
 * from a secure origin and '?runtest' query. That tells us to run the test
 * body, function runTest(). Then we wait for call of finish(). On its first
 * call it loads helper page 'backward.html' that immediately navigates
 * back to the test secure test. This checks the bfcache. We got second call
 * to onload and this time we call afterNavigationTest() function to let the
 * test check security state after re-navigation back. Then we again wait for
 * finish() call, that this time finishes completelly the test.
