Strange behavior after connection change

[admin]

Add this to Custom CSS:

Code:

.offline {
  position: absolute;
  z-index: 9999;
  top: 10px;
  right: 10px;
  padding: 10px;
  background-color: rgba(255, 0, 0, 0.5);
}

And this to Custom JS:

Code:

$(function() {
  if (typeof localbus !== 'undefined') {
    var offline = $('<div class="hide offline"></div>')
      .text('No connection')
      .appendTo('body');

    setInterval(function() {
      offline.toggleClass('hide', !!localbus.ws);
    }, 1000);
  }
});
