Subject: [PATCH 1/3] change hash without affecting the rest of URL

Closes #9955 . Hash change currently replaces history state url with only the updated hash, ignoring the current URL (path, query parameters etc). This PR fixes the hash change method, so that it updates only the fragment (part in case of a named fragment parameter), while leaving the rest of URL untouched.
