• The anchorScroll utility saves the scroll position relative to an element, and then restores it after a callback has been run.

    This is useful if a redraw will change the page's content above the viewport. Normally doing this will result in the content in the viewport being pushed down or pulled up. By wrapping the redraw with this utility, the scroll position can be anchor to an element that is in or below the viewport, so the content in the viewport will stay the same.

    • callback: (() => void)

      The callback to run that will change page content.

        • (): void
