Subject: [PATCH] Use `BaseViewer.previousPage` more in the default viewer (PR
 12870 follow-up)

I missed this one spot in PR 12870, when converting the other cases in the "keydown" event handler. However, given that it only matters in PresentationMode and/or when "page-fit" zooming is enabled, this oversight shouldn't have had any user-observable impact (but we should fix it nonetheless).
