Chord inversion shortcuts broken?

Can anybody confirm the shortcuts for Chord tracks inversion work?

inversion up
inversion down

I am thinking these are supposed to scroll through the inversion options you see in the top info bar, when it’s open.
Mine do nothing on the selected chord in a chord track…

Thank you!

These commands operate on Chords in the Key editor and Score editor, not on the inversions list for chord symbols.
