2D view does not update changes (property bound to custom property)

Steps to reproduce:

1. Create/open a general project
2. Add two rectangles to 2D view
3. Add new property of type Int for rectangle1 in Properties -> User added properties -> +
4. Select rectangle2 in Navigator
5. Select action icon -> Set binding in Properties -> Geometry 2D -> Size W
6. Set binding to rectangle1 new property (rectangle1.property0)
7. -> width of rectangle2 changes to 0 which is expected
8. Select rectangle1 and change the value of the new property to 300
9. -> would expect that the width of rectangle2 would change to 300, but it does not
10. Reset view
11. -> rectangle2 width now updates to 2D
