ui.DatePicker Prev Button not working with showing multiple month and showCurrentAtPos not equal to zero

[Umbrae]

When showing more than 1 month at a time and setting showCurrentAtPos/showCurrentMonthAtPos to be anything but 0, the prev button does not operate (does nothing). Next button will properly advance, but previous has no affect. In the same case (showing multiple months) with showCurrentAtPos and showCurrentMonthAtPos set to zero the previous button works properly as expected.

<script>
$( "#datepicker" ).datepicker({
numberOfMonths: 3,
showButtonPanel: true,
showCurrentAtPos: 1,
showCurrentMonthAtPos: 1
});
</script>
<div id="datepicker"></div>

#15118 is a duplicate of this ticket.

Seems as if showCurrentAtPos is added to offset when refreshing the datepicker, which is not correct. I've already fixed this for me. How can i contribute?
