Datepicker: inconsistent behavior in IE when click to close month and year drop-downs

[rdworth]

Using a datepicker with month and year drop-downs, if you click to expand a drop-down, then click in the same place to collapse it, the focus is set back to the instance element input. Except in IE. In IE, the focus stays on the drop-down.

There is a check to have this code not run in IE.

​http://github.com/jquery/jquery-ui/blob/master/ui/jquery.ui.datepicker.js#L849

  if (inst.input && inst._selectingMonthYear && !$.browser.msie)
    inst.input.focus();

Testing shows this check is there because in IE the first click to expand the drop-down sometimes cause the drop-down to collapse immediately because focus goes from the drop-down to the text input. This can fixed by using a setTimeout 0 instead, so that IE can have the same behavior as other browsers.

Datepicker: use a setTimeout 0 so the same code can run in IE (as other browsers) to set focus back to the datepicker text input if a month or year drop-down is clicked closed. Fixes #5897 - Datepicker: inconsistent behavior in IE when click to close month and year drop-downs
