    sd signature line: preserve current page after signing
    
    Once the user adds a visible signature to a PDF file, we reload the
    document, so what you see on the screen matches what's in the file (and
    you can add a next signature).
    
    Make sure that in case the signature is not on the first page, the
    current page state is preserved.
