Dynamics such as fp not recognised by hairpin logic

Issue type

UX/Interaction bug (incorrect behaviour)

Description with steps to reproduce

Use the dynamics popup to create a p > pp; the hairpin is input as a > because the logic understands that pp is quieter than p:

Now try the same with fp to pp:

The hairpin remains < because seemingly the fp is not understood as 'f then p'; it ought to change to > just as in the previous example.
Same for ffp, sffzp, and similar dynamics.
