Relation editor: Role unintentionally modified removing member from member list

[skyper]

What steps will reproduce the problem?

1. Have a relation with member roles
2. Open relation editor
3. Select member with role in member list by clicking on role field
4. Watch the the role field being active and ready for modification
5. Delete member from list either with "Remove currently selected members from member list" or "Remove all members referring to one of the selected objects"

What is the expected result?

Member is removed from member list but no roles of remaining members are modified

What happens instead?

Role of the member below the removed member is modified

Please provide any additional information below. Attach a screenshot if possible.

Seems to happen all the time if the role field is active for modification, e.g. modifying roles above by typing plus Enter and than removing does trigger it, too.
Noticed this for some time now, but never took the time to fill a ticket, sorry.
