Can't add B above cursor using Option-Shift B on Mac (M1)

I’m not sure if this is the right place to point this out. It’s a minor but persistent frustration.

This is in Dorico SE 3.5.12.1066 on an M1 Mac.

I can’t add B above current note. The Option-Shift works on all other note names, C-A, but does nothing when Option-Shift-B is pressed.

To reproduce, open a new score, Shift-N to go to note entry mode, type any note (say C), and then try Option-Shift-B, and no note is entered.

Yes, this is an annoying but known issue with the Qt framework.

Thanks for letting me know!
