When we add a new listener to an object, it will emit the full state of the object. For this it temporarily sets the change_mask to all changes. Restore the previous state after this or else we might not emit the right change_mask for the next listener. Consider the case where one there are two listeners on an object. The object emits a change and the first listener wants to enumerate the changed params. For this is adds a new listener and then triggers the enumeration. If we set the change_mask to 0 after adding the listener, the second listener would get a 0 change_mask and fail to update its state. |
