// This test runs through an expected use of a live background page:
// - A live (web-extent) web page is loaded (a.html), which opens the background
// page.
// - The first page is closed and a second live web page is loaded (c.html),
// which uses a different name. This second page also checks a counter which
// should have a value consistent with being called once.
// - We then reopen the first page. This first page also checks a counter
// which should have a value consistent with the page being newly opened.
// - The background page closes itself.
