Beyond the symmetry\u2010breaking point localization is gradually restored, although in this regime the power of localized modes grows upon propagation. The strength of localization monotonically increases with disorder at both broken and unbroken <jats:inline-graphic xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" xlink:href=\"graphic\/lpor201500149-math-0004.png\" xlink:title=\"urn:x-wiley:18638880:media:lpor201500149:lpor201500149-math-0004\"\/>\u2010symmetry.
