Notehead parentheses property may become incorrect with linked staves

Issue type

Engraving bug (incorrect score rendering)

Description with steps to reproduce

With a pair of linked staves:

1. Select the note on the top staff and add parentheses.
   RESULT: Parentheses are added to both staves, and the property reflects this correctly.
2. Range-select the note on the top staff and hit R to repeat.
   RESULT: The note is repeated with parentheses on both staves as expected, but the property is reversed for the lower staff.
3. Range-select this note on the lower staff, then copy and paste.
   RESULT: The note is repeated with parentheses on both staves as expected, but now the property is reversed for both staves. Note that this survives reloading the score.
