[Constraint] constraint triggered when opening the component
This happens only when the component is opened after restarting AF3.
When the user opens a component the constraints are triggered. They are triggered because the dashboard is created at that point. This takes longer to open a component than expected.
It is not a bug IMO, more a choice taken during implementation.
