month/year drop-downs don't update input-field (user must explicitly click on day)

[fraktalfabrik]

On ​https://jqueryui.com/datepicker/#dropdown-month-year, if you select a date first, then exit the picker and re-enter and now change just the year (or month) via the drop-down the input field doesn't get updated.

I believe the user expectation is that any changes done in the calendar "popup" are reflected in the input field once the pop-up is closed, ie we don't have to explicitly click the (same) day again if we just want to change day/month.

Adding showButtonPanel: true seems to make no difference either (clicking on 'done' doesn't update the values either)

Tried Chrome and MSIE and both exhibited the same behavior.

Changing those dropdowns is purely a navigational operation. See #8463 for a feature request to implement the behavior you want.
