Accordion symbols do not appear in parts when linked to a rest

[henkdegroot]

Bug description

When an Accordion symbol is place in the mainscore and linked to a rest, it does not appear in the part when this is generated.
Symbols are also placed "in" the staff by default, this is the same behaviour as in MS3 but I wonder if that is correct/desired behaviour as they are not really visible/readable like this.

Mainscore sample:

Part score sample;

Steps to reproduce

1. Create a new score
2. Ensure the Accordion palet is visible
3. Enter some notes and rest
4. Add an Accordion symbol to a rest
5. Click on Parts and open the part
