Piano roll pitch bend on duplicated notes applies pitch bend to original notes and vice verse

[Monospace-V]

Bug Summary

Placing notes on piano roll and duplicating them (using Shift-drag) and then bending pitch of the duplicate bends pitch of original too, and vice versa.

Steps to reproduce

1. Open piano roll and place notes
2. Duplicate notes with shift-drag (Ctrl-C and Ctrl-V do not replicate this issue)
3. Switch to pitch bend mode and edit pitch automation of any note

Expected behavior

Only the note clicked on should change automation.

Actual behavior

The other copy of the note also shows pitch edited.
