Cannot read property 'top' of undefined

Not kind of a bug but an annoying console alert:

Uncaught TypeError: Cannot read property ‘top’ of undefined
jquery.validate.contact.form.js:88

jQuery('html,body').animate({scrollTop: jQuery(id).offset().top},'slow');
changed to
if (jQuery(id).offset()) {
  	jQuery('html,body').animate({scrollTop: jQuery(id).offset().top},'slow');
}

First time I see this “error” so I presume it’s WP or jQuery new version’s “fault”
Just for your consideration to include in next version.
Keep the excelent work! We all luv ya!!!
