This seems like the wrong behavior to me. I select the final bar of notes and add the dynamics. You can see the final ff breaks the multi-bar rest that follows.
In order to not break the mult-bar rest, the final dynamic has to be shifted to the left.
Is this an intentional behavior I’m not understanding? Does Dorico interpret the final dynamic as belonging to the downbeat? It seems like it shouldn’t… at least, it’s not what I would want. Why would it be desirable to show a single empty bar before the multi-bar rest, if the dynamic applies only to actual notes?
