> What is the current behavior? Currently, `Transition` and `CSSTransition` component files import `prop-types` as: ``` import * as PropTypes from 'prop-types'; ``` > What is the expected behavior? All other components and files are importing prop-types in the [expected way](https://github.com/facebook/prop-types#importing): ``` import PropTypes from 'prop-types'; ``` I think a simple PR to just update these two files would suffice so there's consistent importing and usage of `prop-types` throughout.
