the top of the keyboard in a KeyboardAccessory. For a host that is part of a page.
'resize': the host shrinks to the part of the screen the keyboard leaves
(useKeyboardResize), so everything in it stays in view above the keyboard. For a host that
is the page; in a page that scrolls it would fight the page.
'none': nothing; the host or the browser manages the keyboard.
