Calendar: Multiple Month/Year selection mode not highlighting selected month

[melloware]

Describe the bug

Original Report on PrimeReact: primefaces/primereact#4892

After taking a brief look, it seems like the isMonthSelected function in the calendar component is not functioning as it should:

       const isMonthSelected = (month) => {
            if (isComparable()) {
                let value = isRangeSelection() ? props.value[0] : props.value;
                return !isMultipleSelection() ? value.getMonth() === month && value.getFullYear() === currentYear : false;
            }
            return false;
        };

value is an array of dates when the selectionMode is multiple not a single date. Same could be for Years but I haven't checked
