Soft navigations and bfcache restores cause small positive navigationId increments:
between id_2 and id_3:
-> increment is positive
-> increment is small
between id_3 and id_4:
-> increment is positive
-> increment is small
between id_4 and id_5:
-> increment is positive
-> increment is small
between id_0 and id_6:
-> increment is positive
-> increment is small
