Reset Position doesn't affect tuplet bracket

1. Move a tuplet bracket.
2. 'Reset Positions'.

Desired behaviour: The bracket should return to the original place.
Actual behaviour: It doesn't move.

Just a note: If you move a rest, the bracket will move with it. If you click on the rest and 'Reset Positions', the bracket will return to the original position.
