The all-pages switch flushed the active page to Hive first, so a plain side
click wrote every pending edit to disk and "Don't save" could not take the
side change back. Now only the other pages are flipped in place, which is
how they are held between visits anyway, and the active page's side rides
on the normal save like the this-page switch already did.
