[Bug] Constraints will print wrong positions if group is selected under other root screen (frame)

Problem.

The design to code uses constraints to set the position. this should have worked if the selection was frame, but it was group. so each item will reference the root (the screen frame) to it's relative position, which should't in assistant part selection scenario.

This should be fixed by determining the selection relevance to the scree + check if group.
