Lines from palette added by double-click with range selection ignore score style settings
Related to https://musescore.org/en/node/282433 but not the same:
If the .mss contains
ottavaNumbersOnly set to
0, newly created ottavas still don’t show the va or vb text.
Moving one with numbers only disabled in the inspector to a user/custom palette does not help, the property does not show up there.
Workaround is to manually untick numbers only in the inspector after creating an ottava line (ugh…)
