Invisible Volta Lines
After loading an MSS style file the lines of existing voltas are becoming invisible.
The score has been converted from MuseScore 2, the MSS file has also been used in Musescore versions and saved again after some small changes with the current Musescore version.
When I click on one of the volta numbers, the respective volta, including its lines, is selected correctly, the selection just didn't make it into the screenshot.
Increasing the line thickness in the Inspector didn't help.
