-// SaveUIState avoids losing scroll position due to navigation
-// events, and saves/restores other caller-specified UI state.
-//
-// It does not display any content itself: do not pass any children.
-//
-// Use of multiple SaveUIState components on the same page is not
-// (yet) supported.
-//
-// The problem being solved:
-//
-// Page 1 loads some content dynamically (e.g., via infinite scroll)
-// after the initial render. User scrolls down, clicks a link, and
-// lands on page 2. User clicks the Back button, and lands on page
-// 1. Page 1 renders its initial content while waiting for AJAX.
-//
-// But (without SaveUIState) the document body is small now, so the
-// browser resets scroll position to the top of the page. Even if we
-// end up displaying the same dynamic content, the user's place on the
-// page has been lost.
-//
-// SaveUIState fixes this by stashing the current body height when
-// navigating away from page 1. When navigating back, it restores the
-// body height even before the page has loaded, so the browser does
-// not reset the scroll position.
-//
-// SaveUIState also saves/restores arbitrary UI state (like text typed
-// in a search box) in response to navigation events.
-//
-// See CollectionsSearch for an example.
-//
-// Attributes:
-//
-// {getter-setter} currentState: the current UI state
-//
-// {any} defaultState: value to initialize currentState with, if
-// nothing is stashed in browser history.
-//
-// {boolean} forgetSavedHeight: the body height loaded from the
-// browser history (if any) is outdated; we should let the browser
-// determine the correct body height from the current page
-// content. Set this when dynamic content has been reset.
-//
-// {boolean} saveBodyHeight: save/restore body height as described
-// above.
