Simple Crossbrowser textarea expander

Question

My previously simple textarea expander is now causing problems.

$(document).on('keyup', 'textarea',function(){
        $(this).height($(this).prop('scrollHeight'));
    });

Works fine on Firefox but on webkit browsers keeps increasing the text-area in size on every key press whether it needs to or now.
