i am sorry if i am asking stupid question but, issue says Open so does this mean it has not yet been merged into a release?
Many thanks

There is a big optimization that can be done here. Instead of doing a $timeout everytime it changes, scheduling an operation with scope.$$postDigest would batch it. This requires the addition of a boolean check inside the $watchCollection callback, and resetting the flag when the function is executed.

Something like

var foo = false;
scope.$watchCollection('$select.items', function() {
  if (!foo) {
    scope.$$postDigest(function() {
      foo = false;
      repositionUpwardDropdown();
    });
  }
});

This needs rebasing.

This should fix #1007.
