// This test:

// * Does a fragment navigation, then goes back (same-document).

// * Navigates away, then back via bfcache.

// When navigating away, navigation.entries()[1] will be overwritten.

// When returning after bfcache restore, navigation.entries()[1] should represent

// pageB, and the original navigation.entries()[1] should have been disposed.
