monthYear picker value doesn't change if you only change the year.

[TonislavTachev]

The value of the date doesn't change when you only change the year.

Steps to reproduce the behavior:

For instance when you open the datepicker your staring month is January, should you try to change only the year without changing the selected month your value will be empty.

It would be nice if we were able to capture the change only to the month, rather than both.
