[XeTeX] including page 1 of a one page .pdf different from the base file?

[William Adams]

When I pull in a single page .pdf and measure it, I get two different values, depending on whether or no I specify page 1:

\savebox\elementpage{\XeTeXpdffile"HEIelements.pdf"}         % == 650.43pt (correct)
\savebox\elementpage{\XeTeXpdffile"HEIelements.pdf" [page 1]}% ==684.31895 (wrong?!)

\settowidth{\elementpagewidth}{\usebox{\elementpage}}

\the\elementpagewidth

Any idea as to what's happening?
