It seems the code in instruments.h needs to follow the sample in the channel.mute lines to update midiBank and midi.Program as integers range 1 to 16
ie append { activeChannel()->setmidiBank(qBound(1, val, 16)); }
ie append { activeChannel()->setmidiBank(qBound(1, val, 16)); }

   bool mute() const { return _channel->mute(); }
   void setMute(bool val) { activeChannel()->setMute(val); }

   int midiProgram() const { return _channel->program(); }
   void setMidiProgram(int prog);  // < change here ---------------------------------<<
   int midiBank() const { return _channel->bank(); }
   void setMidiBank(int bank);  // < change here ---------------------------------<<

What code exactly (branch, file and line) and where are you talking about? in ...libmscore/instruments.h I find nothing even remotely similar to your description/code snippet (and that isn't the place for code used by plugins anyhow).
And why would this be a bug? Adding the ability of making some setting available to Plugins whould be a Suggestes (AKA feature request)

For the 3.x branch maybe you're talking about mscore/plugin/api/instrument.cpp lines 65-83?
