How to use CKEditor in a Bootstrap Modal?

Question

If I use the CKEditor plugin in an HTML page based on a Bootstrap template, it works great, however if I insert the editor on a Bootstrap Modal like this

<!-- Modal --> 
<div class="modal fade" id="modalAddBrand" tabindex="-1" role="dialog" aria labelledby="modalAddBrandLabel" aria-hidden="true">   
  <div class="modal-dialog modal-lg">
     <div class="modal-content">
       <div class="modal-header">
         <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
         <h4 class="modal-title" id="modalAddBrandLabel">Add brand</h4>
       </div>
       <div class="modal-body">
             <form>
             <textarea name="editor1" id="editor1" rows="10" cols="80">
             This is my textarea to be replaced with CKEditor.
             </textarea>            <script>
             CKEDITOR.replace('editor1');
             </script>
             </form> 
       </div>
       <div class="modal-footer">
         <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
         <button id="AddBrandButton" type="button" class="btn btn-primary">Save</button>
       </div>
     </div>   
   </div> 
</div>

The editor works, but all the form controls on the popup windows of the editor are disabled, if you try to add a link or an image, for example, you cannot insert the URL or any description because the inputs are disabled.

Any workaround for this issue?

This is a fiddle example: http://jsfiddle.net/7zDay/

This should help http://jsfiddle.net/pvkovalev/4PACy/

$.fn.modal.Constructor.prototype.enforceFocus = function () {
    var $modalElement = this.$element;
    $(document).on('focusin.modal', function (e) {
        var $parent = $(e.target.parentNode);
        if ($modalElement[0] !== e.target && !$modalElement.has(e.target).length
            // add whatever conditions you need here:
            &&
            !$parent.hasClass('cke_dialog_ui_input_select') && !$parent.hasClass('cke_dialog_ui_input_text')) {
            $modalElement.focus()
        }
    })
};

Update October 2016:

CDN link for CKEditor has been changed, so I updated jsfiddle
