Adding one slur in a voice in linked staves adds multiple wrong slurs

[Mansent]

Issue type

Engraving bug

Bug description

I have a part with linked staves displaying different voices. If I add a slur, multiple slurs get added that look ugly.

Here is a file which demonstrates the problem:
Bug3.zip

Steps to reproduce

1. Create new empty score with one instrument
2. Enter a few notes in voice 1 and 2
3. Select first note in voice 1
4. ctrl click last note in voice 1
5. press S to slur
6. create a part of that instrument
7. create a linked stave
8. configure the first stave to only show 1st voice, second stave to only show 2nd voice

Now if I select a bar in the lower stave and press S to slur, the additional slurs appear.

Screenshots/Screen recordings

I just tried to slur the second stave and I got this.

As far as I can tell this is a Mu3 regression
