Steps to reproduce:
1. In timeselector select "Today" shortcut.
2. In first datepicker select specific date.
3. Open other datepicker.

Result: It has preselected date from first datepicker.
Expected: It has today's date preselected.

4. Select other specific date within same month.
5. Open first datepicker.

Result: Selected date is highlighted (correct), date from other datepicker is highlighted (wrong).
Expected: Today's date should be highlighted, but the date from other datepicker should not be highlighted.
