		Did you try what Kelly suggested in an earlier post?
var showText =  esriBundle.widgets.overviewMap.NLS_show;
      overviewMapDijit.on("load", function(){
        query('div[title ="' +  showText + '"]').forEach(function(node){
            domAttr.remove(node, "title");
            domAttr.set(node, "data-title", showText);
        });
      });
[data-title]:hover:after {
    content: attr(data-title);
    text-align: center;
    font-family: Arial;
    font-size: 11px;
    font-weight: bold;
    background-color: white;
    border: 1px solid #000000;
    border-radius: 1px;
    padding: 4px 8px;
    left: 40px;
    width: 40px;
    z-index: 20px;
    position: absolute;  
}Can you show an example in Fiddle or JSBin?
