Note input mode is incorrecrly switched for tabulatures and drumsets
Steps to reproduce:
1. Create a score with a treble clef and a tabulature/drumset staff.
2. Enter some input mode (for example, Real-time automatic), ensure it works for the treble clef (play something on virtual piano board or MIDI keyboard for Real-time mode).
3. Click on the tabulature/drumset staff.
4. Switch to the default (Step-time) input mode.
Expected results: input should switch to Step-time mode, Real-time mode is not working.
Actual results: the previous input mode (Real-time in this example) is still working.
Issue #276670: Crash on mouse press on tabulature in Repitch input mode might be also related to this so I suppose fixing this issue can potentially fix that one too.
