Hello,  i have 1 element. He must grow in width, height and border, and he do this. But have problem after when i did reverse (i showed two case) 

1-case(icon-cursor-1): When click start and after complete animation click reverse() (after complete animation reverse) and again click start we see: border width jumping 

2-case(icon-cursor-2): When click start and after complete animation click reverse() (after complete animation reverse) , he don't return primary value for border width (default border width 3px)
