clicking "Today" does not affect calendar view

[_nec]

If I click the "Today" button in the buttonbar, the date value changes, but the calendar does not shows the selected day properly, the last selected day remains active. Can be reproduced at the current demo at ​http://jqueryui.com/demos/datepicker/#buttonbar (Chrome 10, OSX 10.6.6)

hint: "patched" this in my local copy of jquery.ui.datepicker.js

	/* Action for current link. */
	_gotoToday: function(id) {
		var target = $(id);
		var inst = this._getInst(target[0]);
		if (this._get(inst, 'gotoCurrent') && inst.currentDay) {
			inst.selectedDay = inst.currentDay;
			inst.drawMonth = inst.selectedMonth = inst.currentMonth;
			inst.drawYear = inst.selectedYear = inst.currentYear;
		}
		else {
			var date = new Date();
			inst.selectedDay = inst.currentDay = date.getDate();
			inst.drawMonth = inst.selectedMonth = inst.currentMonth = date.getMonth();
			inst.drawYear = inst.selectedYear = inst.currentYear = date.getFullYear();
		}
		this._notifyChange(inst);
		this._adjustDate(target);
	},
