minDate can be maxDate (and vice versa)

[szotsaki]

According to the documentation, minDate and maxDate denote the

Minimum/Maximum limit to selectable date.

According to the docs, the expected behaviour is if minDate is specified greater than maxDate, all dates are disabled.

Common code:

const today = new Date();
const tomorrow = new Date();
tomorrow.setDate(tomorrow.getDate() + 1); // Reproducer works with +2, +3, etc.

Correct behaviour:

new Datepicker(datepicker, {
    minDate: today,
    maxDate: tomorrow
});

Incorrect behaviour:

new Datepicker(datepicker, {
    minDate: tomorrow,
    maxDate: today
});

Result in both cases:
