+ * message to an open BroadcastChannel is used for this.
+ *
+ * First the test opens a window and loads a page there. Another page is then
+ * loaded and then session history is navigated back to check if bfcache is
+ * enabled. If not, close message is sent to close the opened window and this
+ * controller page will finish the test.
+ * If bfcache is enabled, session history goes forward, but the
+ * BroadcastChannel in the page isn't closed. Then sending the message to go
+ * back again should evict the bfcached page.
+ * Close message is sent and window closed and test finishes.
