Navigation between months using previous/next arrows

[hbaccara]

If the the number of days in the current month is higher than the number of days in the previous/next month, the datepicker jumps two months back/ahead when the user selects the last day of the month then clicks prev/next .
For instance, if the user navigates to August, selects the day 31 then clicks the NEXT arrow, the date picker displays October instead of September.
The issue can be fixed by replacing the following in the code:
// Adjust date for month offset
_date.setMonth(_date.getMonth() + _offset);
_date.setDate(Math.min(1, _date._max()));
by the following:
// Adjust date for month offset
_date.setMonth(_date.getMonth() + _offset, 1);
