If useState contains a simple value like string or int, setting a new value that is the same as the existing value will not cause the component to re-render. However, if useState contains an object and I update the state with a new object that contains the exact same values, it will trigger the component to re-render. The React documentation says that is used Object.is to compare values. My 2 objects are identical, so why does the re-render happen?
