Public bug reported:

Firefox 47.0 Mozilla Firefox for Ubuntu canonical - 1.0 
When "href" attribute is removed from <a> on mouseover event, the statusbar in Firefox stays on even after mouse is moved away from the <a> link.


$('#one').on('mouseover', function(evt) {
  $(evt.target).removeAttr('href');
});
