[iOS] landscape PDF wrong initial zoom

[enoiu]

When viewing a PDF in landscape orientation, the PDF does not fit the screen. When I move to the next page, it fits the screen.

According to this pull, the initial zoom bug on iOS seems to have been resolved, but I think this bug has not been resolved for landscape PDFs.
