MonthPickerInput input should not change when Back and Forth button for years is clicked? It is only a navigation feature, User does not mean to change the year when he is navigating. User will click the month, if intended to change the year.

Also, in current implementation of MonthPickerInput, when year back and forth buttons are clicked, input is updated, but change-year event is not fired
