        This addresses a regression introduced by r75784, as described in:
        https://bugs.webkit.org/show_bug.cgi?id=53176

        The problem is that originalEndContainer and originalEndOffset was
        meant to capture the end of the document, but was being assigned after
        a call to searchRange->setStart() (when scoping is restarted), which can
        result in the Range being collapsed to start (thereby assigning the
        wrong value to the Container/Offset pair).

        This code is never triggered by layout tests, but I'm adding a regressiono
        test on the Chromium side for this.
