BYHOUR does not work when STARTDATE does not has time (Attached with unit test code) Appreciate if anyone can help?

    [Test]
    public void SkippedOccurrenceOnWeeklyPattern()
    {
        const int evaluationsCount = 1;
        var eventStart = new CalDateTime(new DateTime(2021, 11, 15, 0, 0, 0, DateTimeKind.Local)); //monday
        var eventEnd = new CalDateTime(new DateTime(2021, 11, 21 , 0, 0, 0, DateTimeKind.Local));//sunday
        var vEvent = new CalendarEvent
        {
            DtStart = eventStart,
            DtEnd = eventEnd,
            Duration = new TimeSpan(0,1,0,0)
        };

        var pattern = new RecurrencePattern
        {
            Frequency = FrequencyType.Weekly,
            ByDay = new List<WeekDay> { new WeekDay(DayOfWeek.Monday) },
            ByHour = new List<int>() { 2 }
        };

        vEvent.RecurrenceRules.Add(pattern);
        var calendar = new Calendar();
        calendar.Events.Add(vEvent);

        var intervalStart = eventStart;
        var intervalEnd = intervalStart.AddDays(7 * evaluationsCount);

        var occurrences = RecurrenceUtil.GetOccurrences(
            recurrable: vEvent,
            periodStart: intervalStart,
            periodEnd: intervalEnd,
            includeReferenceDateInResults: false);
        var occurrenceSet = new HashSet<IDateTime>(occurrences.Select(o => o.Period.StartTime));

        Assert.AreEqual(evaluationsCount, occurrenceSet.Count);

        var observed = occurrenceSet.FirstOrDefault().AsDateTimeOffset;
        var expected = new CalDateTime(2021, 11, 15, 2, 0, 0).AsDateTimeOffset;
        var isEquals = observed.Equals(expected);
        Assert.IsTrue(isEquals, $"Expected {expected.ToString("s")}, but Observed {observed.ToString("s")}");
    }

Attached with the unit test.

Expected 2021-11-15T02:00:00, but Observed 2021-11-15T00:00:00

Suspect the issue caused by this method

ical.net-master\src\Ical.Net\Evaluation\RecurrencePatternEvaluator.cs
method HashSet Evaluate(IDateTime referenceDate, DateTime periodStart, DateTime periodEnd, bool includeReferenceDateInResults)

The TIME of expected occurrence somehow goes missing
