Fix UI Bootstrap collapse for ngAnimate 1.4

gistfile1.js

angular.module('ui.bootstrap.collapse', [])

  .directive('collapse', ['$animate', '$animateCss', '$timeout', function ($animate, $animateCss, $timeout) {

    return {
      link: function (scope, element, attrs) {
        function expand() {
          element.removeClass('collapse').addClass('collapsing');

          // Old code that doesn't work anymore with ngAnimate 1.4
          /*$animate.addClass(element, 'in', {
            to: { height: element[0].scrollHeight + 'px' }
          }).then(expandDone);*/

          var animation = $animateCss(element, {
            addClass: 'in',
            to: { height: element[0].scrollHeight + 'px' }
          });

          animation.start().done(expandDone);
        }

        function expandDone() {
          element.removeClass('in collapsing');
          element.css({height: 'auto'});
        }

        function collapse() {
          element
            // IMPORTANT: The height must be set before adding "collapsing" class.
            // Otherwise, the browser attempts to animate from height 0 (in
            // collapsing class) to the given height here.
            .css({height: element[0].scrollHeight + 'px'})
            // initially all panel collapse have the collapse class, this removal
            // prevents the animation from jumping to collapsed state
            .removeClass('collapse')
            .addClass('collapsing');

          // Old code that doesn't work anymore with ngAnimate 1.4
          /*$animate.removeClass(element, 'in', {
            to: {height: '0'}
          }).then(collapseDone);*/

          var animation = $animateCss(element, {
            addClass: 'in',
            to: { height: '0' }
          });

          animation.start().done(collapseDone)
        }

        function collapseDone() {
          element.css({height: '0'}); // Required so that collapse works when animation is disabled
          element.removeClass('in collapsing');
          element.addClass('collapse');
        }

        scope.$watch(attrs.collapse, function (shouldCollapse) {
          if (shouldCollapse) {
            collapse();
          } else {
            expand();
          }
        });
      }
    };
  }]);

I tried with the fixed code, still get a glitchy "go to zero first" then animate from original value. is this a known issue?
