Can't change input modes with keyboard from Percussion Panel

Issue type

Accessibility issue (e.g. for keyboard-only or screen reader users)

Description with steps to reproduce

When focused on the drum pad pressing N or your assigned shortcut for input by duration seem to have no effect and give no speech feedback.

STEPS:

1. Create a score with a drum kit and navigate to that staff. Press tab several times to get to the drum pad.
2. Press your assigned shortcut for input by duration mode (Note: there is no default shortcut so you need to have previously assigned one). Notice there is no speech feedback.
3. Press Esc to jump back to the score and press the shortcut again to check whether it had previously changed. You hear "live live".
4. Press it again several times while on the score and note the usual wording is "input by duration mode" and "normal mode" as it toggles off.
   I am unsure whether this is not changing or just not speaking.

• This report follows the guidelines for reporting bugs and issues

Start by reproducing the issue in the Percussion Panel with a drum kit, keyboard focus, an assigned input-by-duration shortcut, and NVDA on Windows. Compare shortcut state changes and speech feedback in the drum pad versus the score, then verify that toggling modes from the panel produces the expected spoken wording.
