[Musicxml Export] - Missing spanners caused by spanner stop not in the first track
I just finished transcribing this piece. Since I can't reproduce the problem snippet myself, I have to attach all the score. Generally, I found lots of hairpins missing when exporting to Musicxml. For example, (below I count from the first complete measure), m8-9, there are lots of missing hairpins when using the fixed Musescore 3 file, including some woodwinds, horns and strings. When I use the old Musescore 2 file, the hairpins are there. I export both scores using Musescore 3.3 rc, and the problem is the same. I checked the Musescore file code, and both files don't hide such hairpins in these measures. I suspect all braille scores I have published may be effected by this strange problem, and for this work, I have to check the braille bar by bar using the old file. What's wrong with the export? Thank you in advance!
