/**
 * The useCombobox version of useControlledReducer, which also
 * checks if the controlled prop selectedItem changed between
 * renders. If so, it will also update inputValue with its
 * string equivalent. It uses the common useEnhancedReducer to
 * compute the rest of the state.
 *
 * @param {Function} reducer Reducer function from downshift.
 * @param {Object} props The hook props, also passed to createInitialState.
 * @param {Function} createInitialState Function that returns the initial state.
 * @param {Function} isStateEqual Function that checks if a previous state is equal to the next.
 * @returns {Array} An array with the state and an action dispatcher.
