As title suggests. To reproduce. set minDate to new Date(), maxDate to new Date().increment("day", 30);. open date picker, in the current month view, pick a date from next month, eg, 6th. Open it again, the disabled dates have not reset even though it now goes to next month.
new Date().increment("day", 30);
temp fix is via forcing a re-render of days after select in Picker.Date.js on line 316 after this.date = date;:
this.date = date;
