Issue #3292032 by pivica: Collapse region is always hidden rule is problematic

  // When navbar collapse responsive break is the largest breakpoint then we

  // need to modify displays of navbar collapse region and toggler.

  @if breakpoint-max($navbar-collapse-responsive-break) == null {

    // Collapse region is always hidden except when it is in screen.

    .region-navbar:not(.in) {

      display: none !important;

    }

    // Toggler is always shown.

    .navbar-toggler {

      display: block !important;
