With Next.js scrollRestoration set to manual, going back from an in-page fragment left the URL correct but kept the hash scroll position. Save scrollY on the history entry before hash navigation and restore it on popstate. Fixes reactjs#787. Co-authored-by: Cursor <cursoragent@cursor.com>

Details
The global bundle is the javascript bundle that loads alongside every page. It is in its own category because its impact is much higher - an increase to its size means that every page on your website loads slower, and a decrease means every page loads faster.
Any third party scripts you have added directly to your app using the <script> tag are not accounted for in this analysis
