Broken ng-model binding in 2016.2.714

[Marcel]

Using the latest version in combination with angular 1.5.8 using components it appears that the multi-select doesn't show anything when i use an ng-model binding.
I created an example at http://dojo.telerik.com/@Marcel/osoHA/2 to show you the problem.
I know i can use k-ng-model to successfully bind, but that raises other problems in my application due to custom directives that require ng-model, angular validation, etc.

Is this a known (broken) issue and is there a workaround to solve this problem ?

i eventually found out i can use the $postLink method to set the value of the multi-select so it reflects the ng-model.

vm.$postLink = function () {
  $scope.keySelector.value(vm.keys);
}

However, now i'm running into other problems using ng-required when the initial binding is an empty array.
It stays valid until i add and remove an item.
