I recentrly started using the material.angular.io components on my app: https://material.angular.io/components/component/button-toggle
Im seeing in the doc that the button-toggle component has an @Input property called selected that is not setting as selected my button like the disabled property is setting as disabled the other one... I'm doing something wrong?
