(Lack of) Hairpin/Dynamic Independence

1) Create music for (minimum) two instruments
2) For one instrument (A), on a given beat, begin a hairpin into a dynamic ("Dynamic A1")
3) After a rest, have the instrument A re-enter at a different dynamic ("Dynamic A2")
4) For another instrument (B), begin a hairpin, on the same beat, into a dynamic ("Dynamic B"). This hairpin needs to last past instrument A's re-entrance.

Expected Behavior: Instrument A (de)crescendos to dynamic A1, then re-enters at dynamic A2, as instrument B (de)crescendos to dynamic B.

Actual Behavior: Instrument A (de)crescendos to - and re-enters at - dynamic A1, until B reaches dynamic B. At this point, Instrument A jumps up/down to dynamic A2.
