Subject: [PATCH] LibWeb: Scroll to the top after navigating to a new document

This change fixes a bug with running tests where, if one of the
previous tests changes the scroll position, all subsequent tests that
rely on the scroll position will fail. This is because the headless
browser never resets the viewport offset.
