find a wordaround to resolve the problem.

textarea.addEventListener('scroll', function(evt){
    evt = evt || window.evt;
    evt.target.setSelectionRange(evt.target.textLength - 1, evt.target.textLength - 1);
    setTimeout(function(){
        evt.target.setSelectionRange(evt.target.textLength, evt.target.textLength);
    }, 0);
});
