Scribble to fix scroll position

_app.tsx

const cachedScrollPositions: {
  [asPath: string]: { x: number; y: number };
} = {};

/**
 * - Save the scroll position mapped to the current url on navigation
 * - Mark shouldScrollRestore on beforePopState to trigger scrollTo only for back/next navigation
 * - Remove scroll position when normally navigating in: Refresh, links
 * - (Re-)trigger scrollTo after all content is loaded with triggerScroll
 *
 * Inspired by https://github.com/zeit/next.js/issues/3303#issuecomment-562581796

@sahar75 Probably replace window.scrollTo with document.getElementById('YOUR_DIV_ID').scrollTo

And window.scrollX, etc. accordingly

@sahar75 Probably replace window.scrollTo with document.getElementById('YOUR_DIV_ID').scrollTo

that doesn't work unfortunately
