Can't trigger animation on nested ngRepeat

I can't figure out how to trigger animations on a nested ngRepeat with Angular.

The CSS class ".test" is animated. When using ".test" on the inner ngRepeat it doesn't work (Plunker):

<div ng-repeat="section in sections">
  <div ng-repeat="item in section.items" class="test">
    <h2>{{item.title}}</h2>
  </div>
</div>

When using ".test" on the outer ngRepeat it does work (Plunker):

<div ng-repeat="section in sections">
  <div ng-repeat="item in section.items" class="test">
    <h2>{{item.title}}</h2>
  </div>
</div>

You probably need to add ngAnimateChildren attribute on the parent container, and update the css as well.

Try:-

<div ng-repeat="section in sections" ng-animate-children>
  <div ng-repeat="item in section.items" class="test">
    <h2>{{item.title}}</h2>
  </div>
</div>

and 

.test.ng-move,
.test.ng-enter,
.test.ng-leave {
  -webkit-transition: all 0.3s  ease-out;
    transition: all 0.3s  ease-out;
}

.test.ng-leave.ng-leave-active,
.test.ng-move,
.test.ng-enter {
   opacity:0;
   -webkit-transform: translate(-20px, 0);
    transform: translate(-20px, 0);
}

.test.ng-leave,
.test.ng-move.ng-move-active,
.test.ng-enter.ng-enter-active {
 opacity:1;
   -webkit-transform: translate(0, 0);
    transform: translate(0, 0);
}

Found this from the doc

Keep in mind that, by default, if an animation is running, any child elements cannot be animated until the parent element's animation has completed. This blocking feature can be overridden by placing the ng-animate-children attribute on a parent container tag.

Even though there is no animation on the parent repeat, it seems like ng-animate just ignores any further animation on its children.
