/**
 * This helper utility is meant to be used with the flyout navigation or modals.
 * It traps focus inside the opened or overlaying component per WCAG spec.
 *
 * Some trap focus examples only focus on Tab and Shift+Tab, but many screen readers
 * browse differently, in caret mode, with arrow keys. As a result, these traditional
 * trap focus methods are insufficient. We need to hide everything outside the overlay
 * from screen readers and make it not focusable. This means applying 'aria-hidden'
 * and 'tabindex=-1' to all elements not within the modal. Once the modal is closed
 * we need to remove these attributes.
