Bug: fpp in creschendo chain doesn't play back as expected.

Initial dynamic: mf

In the passage in question there is a crescendo to fpp, then another crescendo, then a decrensedo to pp. After tge fpp the playback dynamics don’t drop at all, and then decrease to pp at the end. The “middle” pp is lost.

Combined dynamics like fpp, and force dynamics like sfz/rfz, currently have no effect during playback. This is something that will be addressed in a future version.
