When using the has-feedback class on a form and if the label on the form group is not specified then it does not render correctly.

<form>
    <div class="form-group has-success has-feedback">
        <input type="text" class="form-control" id="inputSuccess2"> 
        <span class="glyphicon glyphicon-ok form-control-feedback"></span>
    </div>
</form>

The above code renders like this.
