Chord symbols with a bass extension don't export to MusicXML correctly (nor import back)
Had issue with exported files from different projects so tried creating new score.
Done the same with two MIDI files.
1) Created new score in musescore
2) Copied notes from midi.
3) ran Chord Identifier(pop,Jazz)
4) Export file as mxl (MusicXML)
load in Finale - get XML error "the content of element type "Harmony" must match ..."
Load in Dorico - get MusicXML validation failed (ERROR - Element 'bass': this element is not expected. ...)
