 * This hook is used to provide all the menu functionality within the `Menu`

 *
 * - the menu will be closed if an element outside of the menu is clicked
 * - the menu items within the menu are keyboard focusable after typing or using
 *   the arrow keys
 * - the menu will close if the Escape key or Tab key is pressed (tab since
 *   it'll lose focus)
 * - conditionally close the menu if the page is scrolled while visible.
