ng-switch is not working when i use ng-switch-when-separator .
when I select settings the switch is pointing to default div
angular.module("myModule", [])
 .controller("myController", function ($scope) {
    $scope.items = ['settings', 'home', 'options', 'other'];
    $scope.opt = $scope.items[0];
  });
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<body ng-app="myModule">
    <div ng-controller="myController">
        <select ng-model="opt" ng-options="item for item in items">
        </select>
        <code>selection={{opt}}</code>
        <hr />
        <div class="animate-switch-container"
            ng-switch on="opt">
            <div class="animate-switch" ng-switch-when="settings|options" ng-switch-when-separator="|">Settings Div</div>
            <div class="animate-switch" ng-switch-when="home">Home Span</div>
            <div class="animate-switch" ng-switch-default>default</div>
        </div>
    </div>
</body>
