Create a Composite App with some properties and actions and do some wiring.
Then rename one property you have a wire for.
Go into wiring: you get a message that a wire is faulty and you have the button “delete wires”. After clicking this button and using the button “View All Wires…” you see that the wire is not present anymore.
Save and close wiring, open wiring again: you get the message about the faulty wire again.
The wire is NOT deleted.
