Musescore does not save Stacking order for glissandos
Steps to reproduce
1) Write down two notes and put a glissando between them
2)Select the glissando and change its stacking order on inspector (I need that for masking it over time signatures). Default value is 6200. Change it to any smaller number.
3)Save and close score.
4) Reopen it.
Original value for stacking order is back.
