problem with dynamics line

A diminuendo between "piano" and "forte" causes the "forte" dynamic to happen early. The file is annotated. No notes, rests, dynamics, or dynamics lines have any manual velocities. The problematic measure was created in musescore 2.0.3, and consistently plays back incorrectly. I haven't been able to duplicate the problem - an exact recreation (adjacent to the problematic measures; see the file) plays as expected.
