By force-quitting the browser while the FullScreen API is active, we don't get a chance to exit PresentationMode cleanly and some of its state thus remains (via the
ViewHistory
). To try and improve things here we can skip updating the Scroll/Spread-mode while PresentationMode is active, since they will be changed when entering PresentationMode, which seems to help and is really the best that we can do here (and what the issue describes is very much an edge-case anyway).
