// An element fragment anchor is a FragmentAnchor based on a single element.
// This is the traditional fragment anchor of the web. For example, the fragment
// string will be used to find an element in the page with a matching id and use
// that to scroll into view and focus.
//
// While the page is loading, the fragment anchor tries to repeatedly scroll
// the element into view since it's position may change as a result of layouts.
// TODO(bokan): Maybe we no longer need the repeated scrolling since that
// should be handled by scroll-anchoring?
