Here is a more recent discussion on this known issue. The long story short though, there is no good way around it even on our side, so at the moment it’s categorised as a bug in the programming framework rather than something we can fix, unfortunately.
By the way what I would prefer to do is leave page flow to after compiling, using the method described in this post. It’s the “right” way to do this anyway, rather than inserting manual page breaks like Scrivener does. You’ll avoid other odd issues that can arise from doing so that are harder to find.
