Port position in scaled diagram.box wrong

Dear all,
I am working with MPS Diagram Support, Version 2022.2.2705.43ab68d

The position of the ports of a diagram.box (de.itemis.mps.editor.diagram.structure.CellModel_DiagramNode) is incorrect if the box is scaled. The position seems to be unaware of the owning box being scaled.

This picture is taken from a simple example of KernelF. The block 'nested' has been scaled using the mouse. But the out port remains at its position ...

Probably easy to fix ... if you know where to look at ;-)

Thanks and Best Regards,
Andreas/Wurzel

Start with de.itemis.mps.editor.diagram.structure.CellModel_DiagramNode and reproduce the issue in the simple KernelF example using a mouse-scaled block. Trace how the owning box scale is applied to port positions; done means the out port remains aligned with the scaled box.
