Steps to reproduce

1. Use the latest version of Vanilla Calendar Pro.
2. Add selectedDates: [date] to the settings. date must be a JS Date object.
3. Use date.toDateString() and log to the console to see the expected date
4. Compare the log with the selected date in the widget. They are not the same

Expected behavior
The two dates should be the same.
