This is a legitimate error.

It is surprisingly difficult to tell if an element is visible on an HTML page. You basically have to traverse up the DOM tree checking to see if the element or any parent element has a css property of 'display:none'.

You could just wrap the calling code with a 

try { 
  element.focus(); 
} 
catch (ex) { }

Or if you are using something like jQuery

if ($element.is(':visible')) {
   $element.focus();
}
