Moving curved diagram connector straightens it

[Vitaly "_Vi" Shukela]

1. Start Inkscape
2. Create two rectangles
3. Create diagram connector between them
4. Use "Edit paths by notes" to curve it.
5. Select all 3 objects
6. Move all that objects.

What happens:
Rectangles moved, connector moved as well, but it became straight.

What should happen:
Everything moved, connector is still curved.

Partial workaround:
6. Group all that objects
7. Move the group.

But if I "ungroup" them, connectors will straight up too.

Not supported by connectors in current Inkscape versions.
