Hairpin layout on second voice on last measure is not preserved when reopening score
Tested on OS: Windows 10 (10.0), Arch.: x86_64, MuseScore version (64-bit): 184.108.40.20634, revision: 7ea61d9, from the latest MuseScore available at Microsoft Store.
1) Create a second voice on last compass so to add two rests and be able to put a crescendo hairpin until half of it and a diminuendo hairpin from middle to end of it. Just to be clear, the positioning was automatic and made accordingly to "https://musescore.org/en/handbook/hairpins#adjust-length" , the diminuendo hairpin was linked to the rests on the second voice, and the rests were set as invisible;
2) Verify the diminuendo hairpin is automatically placed correctly (test.png shows how it should appear);
3) Save the score (test.mscz is the result);
4) Reopen the score;
5) Verify the diminuendo hairpin lost its shape (opened.pgn shows how it appears).
