=head2 Back and misc. internal fields
RT ticket #8109 reported that back() is broken after reload(), and
that the cookie_jar was also damaged by back(). We test for that:
reload() should not alter the back() stack, and the cookie jar should
not be versioned (once a cookie is set, hitting the back button in a
browser does not cause it to go away).
=cut

ok( $mech->back(), 'Back should succeed' );
is($mech->title, $title, 'reload() does not push page to stack' );
ok(defined($mech->cookie_jar()),
'$mech still has a cookie jar after a number of back()');
# Now some other weird stuff. Start with a fresh history by recreating
# $mech.
