Steps to reproduce

1. Create a range slider inside <uib-accordion-group>
2. Open accordion by clicking the according heading
3. Click on any of the control points/handles.
4. The handles change their place (flicker).
   (I also tried to use $scope.$$postDigest instead of $timeout inside refresh method but that completely makes it dysfunctional).

I am using refresh method on the ng-cllick event of accordion heading:

<uib-accordion close-others="true">
      <uib-accordion-group is-open="isOpen">
        <uib-accordion-heading>
          <a ng-click="refreshSlider()">Range Slider</a>
        </uib-accordion-heading>
        <rzslider rz-slider-model="minRangeSlider.minValue" rz-slider-high="minRangeSlider.maxValue" rz-slider-options="minRangeSlider.options"></rzslider>
      </uib-accordion-group>
    </uib-accordion>

  $scope.refreshSlider = function() {
    $timeout(function() {
      $scope.$broadcast('rzSliderForceRender');
    });
  };

Expected behaviour

The handles should not flicker / change their original place on clicking first time

Actual behaviour

The handles are flickering / changing their original place on clicking first time
