Anything else we need to know

Support specifying display and content-visibility in animations. This support allows for developers to create exit animations after which the element automatically becomes display: none or content-visibility: hidden without needing to write any javascript to handle that switch after the animation is finished. This allows exit animations for elements to be added purely in CSS.
