Nashville Numbers Rendering Modifiers incorrectly with chords_jazz.xml

Describe the bug
Nashville Numbers render correctly with chords_std.xml, but when switching to chords_jazz.xml, the font size of chord modifiers (slash, sus, minor, etc.) is extremely small.

To Reproduce
Steps to reproduce the behavior:

1. Create new file
2. Enter Nashville Numbers with modifiers such as minor, sus or slash (Add -> Text -> Nashville Number)
3. Change Style to Jazz (Format -> Style -> Chord Symbols -> Jazz)
4. See error

Expected behavior
Chord modifiers should be sized according to the Chord, same as when using the default chord style in chords_std.xml

Additional context
I suspect this is a problem with chords_std.xml, since chords_std.xml works just fine, but I can't work out where the file sets the size of the chord modifiers.
