Return the sharing journey to the page Accept lives on

renders for a delegate in their own record. It left the browser there, and the
next step clicks Accept, which lives on the access page. The click waited out
its timeout against a page that does not carry the button.

An assertion inserted mid-journey has to restore the state it borrowed.
