+ /* This test is hard to follow so here a quick description of what it is about.
+ * We want to test that when BroadcastChannel is used in a bfcached page,
+ * this page is fully removed by bfcache.
+ *
+ * To test it we have 2 pages (testUrl1 and testUrl2).
+ * The steps are:
+ * - we show testUrl1. When this is shown page1Shown is called.
+ * - page1Shown creates a BroadcastChannel object, then it loads testUrl2.
+ * - page2Shown is called by testUrl2.
+ * - Based on expectedPersisted we use or not the BroadcastChannel object of
+ * testUrl1.
+ * - Then we call history.back() and testUrl1 will be loaded again.
+ * - when page1Shown is called by testUrl1, if BroadcastChannel has been used
+ * when testUrl2 was shown, we want event.persisted be false, otherwise
+ * true.
