Potential Bug with next()

Potential Bug with next()


I sent this to the wrong group earlier, sorry for what appears to be a double post.
Please see the sample code below.  Running it in FF and checking the console should give you the error I am seeing.  I know the code is pretty weird - it is simply an experiment.  But when I warp a retrieved Comment node (using contents) and do .next() it seems to skip the actual sibling it should get.  Is this a bug?
<html>
    <head>
        <script src="http://code.jquery.com/jquery-latest.js"></script>
        <script>
          $.annotated = function(filter, root){
              if(filter){
                filter = (filter.constructor == String)?[filter]:filter;
              }
              var annotations = $(root || document).find('*').andSelf().contents(
                "[nodeType=8][nodeValue^=@]"
              );
              var annotated = annotations.map(
                function(){
                  var target = $(this).next();
                  console.log(".next() ==" , target)
                  console.log("but nextSibling ==", this.nextSibling)
                  return target;
                }
              );
              return $( $.unique(annotated.get()) );
          }
          $(function(){
            $.annotated()
          });
        </script>
    </head>
    <body id="body">
        <form id="frm1">
            <input id="text001" type="text" /><br/>
            <!--@Constraints({mandatory:true})--><input id="text002" type="text"/><br/>
        </form>
    </body>
</html>
