/**
 * This hook will hide all sibling elements from assistive technology. Very useful for modal
 * dialogs. This will set `aria-hidden` for sibling elements of the provided PopupModel's
 * `state.stackRef` element and restore the previous `aria-hidden` to each component when the
 * component is unmounted. For example, if added to a Modal component, all children of
 * `document.body` will have an `aria-hidden=true` applied _except_ for the provided `stackRef`
 * element (the Modal). This will effectively hide all content outside the Modal from assistive
 * technology including Web Rotor for VoiceOver for example.
 *
 * This should be used on popup elements that need to hide content (i.e. Modals).
