[UI] Pasted model elements should be selected
After a set of copied model elements has been pasted, the new copy should be selected in the corresponding diagram editor. This allows to the user to easily move the new copy in order to avoid overlaps in the graphical layout of the model.
Steps to test:
- Open a component architecture
- Select one or more components
- Copy (e.g., CTRL+C)
- Clear the selection (see #2347)
- Paste (e.g., CTRL+V)
- Observe that the copy overlaps the original, and that there is no easy way to fix the layout.
