Note that the bookmarks from "FORGE Anniversary Edition V1.1.2.pdf" contain embedded destination parameters, meaning they override my PDF reader's default settings (e.g. fit width) with what's in the bookmark (fit page).
I would suggest/request updating the PDF and removing those embeddings, to allow each user to navigate the PDF how they prefer.
Mozilla Firefox's PDF reader for example has a config option, "pdfjs.ignoreDestinationZoom" which helps me override this aspect.
However, apps like SumatraPDF don't have that capability.
Cheers!
