/**
 * Timeout issues adding css animations to enter may be related to
 * https://github.com/reactjs/react-transition-group/issues/189 or
 * https://github.com/reactjs/react-transition-group/issues/22
 * my VM isn't good enough to debug accurately and get a better answer.
 *
 * As a result, use enter 0 so that is-open is applied once entered
 * it doesn't matter if we know when the css-animation is done on entering
 * for exiting though, give time for the css-animation to play
 * before removing from the DOM
 * **note** hitting esc bypasses exit animation for anyone testing.
