/**
 * Love them or hate them, `<Modal />` provides a solid foundation for creating dialogs, lightboxes, or whatever else.
 * The Modal component renders its `children` node in front of a backdrop component.
 *
 * The Modal offers a few helpful features over using just a `<Portal/>` component and some styles:
 *
 * - Manages dialog stacking when one-at-a-time just isn't enough.
 * - Creates a backdrop, for disabling interaction below the modal.
 * - It properly manages focus; moving to the modal content, and keeping it there until the modal is closed.
 * - It disables scrolling of the page content while open.
 * - Adds the appropriate ARIA roles are automatically.
 * - Easily pluggable animations via a `<Transition/>` component.
 *
 * Note that, in the same way the backdrop element prevents users from clicking or interacting
 * with the page content underneath the Modal, Screen readers also need to be signaled to not to
 * interact with page content while the Modal is open. To do this, we use a common technique of applying
 * the `aria-hidden='true'` attribute to the non-Modal elements in the Modal `container`. This means that for
 * a Modal to be truly modal, it should have a `container` that is _outside_ your app's
 * React hierarchy (such as the default: document.body).
