* is loaded to the window. The initial load of that second page doesn't do
* a redirect. Now another non-redirecting page is loaded. Then
* history.go(-2) and history.forward() are called. The second time
* the second page is loaded, it does a redirect. history.back() and
* history.forward() are called again. The page which did the redirect
* shouldn't be accessed, but the page which it redirected to.
* Finally history.forward() is called again and the third page should be
* loaded and history.length should have the same value as it had when the
* third page was loaded the first time.
