Transclusion (true) - Combining values

Consider the following code (http://jsbin.com/IfejIWES/1/):

HTML:

<!DOCTYPE html>
<html ng-app="myApp">
<head>
<script src="http://cdnjs.cloudflare.com/ajax/libs/angular.js/1.1.3/angular.min.js"></script>
<meta charset=utf-8 />
<title>JS Bin</title>
</head>
<body>
  <div ng-controller="MyCtrl">

    <div my-directive>
        <button>some button</button>
        <a href="#">and a link</a>
    </div>
</div>
</body>
</html>

JS:

var myApp = angular.module('myApp',[]);

function MyCtrl($scope) {
    //$scope.log=[];   
}

myApp.directive('myDirective', function(){
    return{
        transclude: true,
        template: '<div class="something" ng-transclude> This is my directive content</div>'
    };
});

Using version 1.1.3 of AngularJS, the output combines the button and anchor from my-directive (in the HTML) with the template inner text 'This is my directive content'.

If I change the version to 1.2.1 the my-directive content replaces the template inner text.

Is there a way to have angular 1.2.1 (and later) do the older behavior?

The link provided by Jeff Hubbard (thanks Jeff) started me in the right direction. From the comments of that post somebody (https://github.com/angular/angular.js/commit/eed299a31b5a6dd0363133c5f9271bf33d090c94#commitcomment-4685184) posted a work around: http://plnkr.co/edit/EjO8SpUT91PuXP0RMuJx?p=preview

Essentially, you can get the old behavior back by changing the JavaScript to use the transcludeFn function in a separate directive. See below my updated code:

var myApp = angular.module('myApp',[]);

function MyCtrl($scope) {

}

myApp.directive('myDirective', function(){
    return{
        transclude: true,
        template: '<div class="something" ng-transclude-append> This is my directive content</div>'      
    };
});

myApp.directive('ngTranscludeAppend', function() {
  return function(scope, element, attrs, ctrl, transcludeFn) {
      if (!transcludeFn) return;

      transcludeFn(function(clone) {
        element.append(clone);
      });
    };
});

Link to my updated jsbin: http://jsbin.com/IfejIWES/3/

One last note, I tried embedding the transcludeFn in my link function directly like:

link: function(scope, element, attrs, ctrl, transcludeFn) {          
  transcludeFn(function(clone) {
    element.append(clone);
  });
}

But this had the effect of creating the button and anchor twice. Moving it out into its own directive solved it for me.

No. This was a very intentional change. See this commit.
