Remove (if exists) entry from list if it'll be pulled as highlight

The problem with only hiding it is that, after moderating the (visible) highlighted one, the html of $( '.articleFeedbackv5-feedback[data-id='+id+']' ) will be replaced with fresh html. If we only hide the original entry, it will also match that selector, have it's html replaced, return to visible state and all of a sudden the feedback will be visible twice (once the original entry in list, once the highlighted one on top)
