[MU4 Issue] In "Edit drumset", custom notehead setting is not maintained when entering notes with the piano

Describe the bug

Noteheads set in Edit Drumset, apart from standard, do not seem to register in the score.

To Reproduce

1. Create a new score with a drumset.
2. In note input mode, click on the Edit Drumset button.
3. Put the instruments in MIDI number order.
4. Click on A1 and name "Met click". Make notehead a cross. Leave other properties unchanged.
5. Click on A#1 and name it "Met. bell". Keep notehead as standard. Leave other properties unchanged.
6. Click OK.
7. Now apply both click and bell to the score using the on-screen Piano keys A1 and A#1.

RESULT: Both notes have standard noteheads.

Expected behavior

The met click in this case should have a cross notehead.
