This is a flaw in how the widgets have been implemented. When they serve as both the view and the controller, a common misarchitecture is to “loop back” a value change in the view back into the controller. This loop should _only_ happen as a result of the user interacting with the UI. To fix this, the controller does not modify its value authoritatively. Rather, it makes a request of the model to change the value it represents, then gets a confirmation or correction from the model once the logical state of the application has stabilized.
