message: fix(floating-menu): support for modal
  This change adds support for floating menus in modal by ensuring that
  floating menu body is in between `<bx-modal>`'s focus sentinels.
  Otherwise, an attempt to focus on floating menu body interferes with
  `<bx-modal>`' s focus-wrapping behavior that attemps moving focus back
  in modal content.
