Сбой в async анимации увеличения кнопки

Столкнулся с такой проблемкой. На форме есть 4 кнопки при наведении которой они увеличиваются в ширину . Так вот я использовал async чтобы плавно её анимировать , вроде получилось как надо , но собственно проблема : При быстром наведении на все кнопки они начинают хаотично увеличиваться в размере не достигая нужного размера

Как выглядит после медленного наведения на все кнопки
