Description

This MR fixes #2360 by handling properly all x-editors that are sharing the same env or depends on the same setup node.

Changes

• improve handling of setup and shared envs to bootstrap from scratch all related editors
• manually test that everything works as expected (as it's hard to do an integration test here)

Checklist

• I have checked make build works locally.
• I have created / updated documentation for this change (if applicable).
