Unexpected behavior IMAP ListMessages with maxNumberOfMessages, MailQuery (ByDateTime)

Hello,

When I’m trying to list messages using ImapClient (from a Gmail IMAP server) I get some unexpected behavior when supplying a MailQuery with DateComparisonType.ByDateTime and maxNumberOfMessages.

Example:

var queryBuilder = new ImapQueryBuilder();
var date = new DateTime(2022, 1, 12, 16, 0, 0);
var query = queryBuilder.InternalDate.Since(date, DateComparisonType.ByDateTime);

var m1 = await Client.ListMessagesAsync("Inbox", query, 1).ConfigureAwait(false);
// m1.Count == 0
var m2 = await Client.ListMessagesAsync("Inbox", query, 10).ConfigureAwait(false);
// m2.Count == 0
var m3 = await Client.ListMessagesAsync("Inbox", query, 50).ConfigureAwait(false);
// m3.Count == 0
var m4 = await Client.ListMessagesAsync("Inbox", query, 100).ConfigureAwait(false);
// m4.Count == 0
var m5 = await Client.ListMessagesAsync("Inbox", query, 200).ConfigureAwait(false);
// m5.Count == 67
var m6 = await Client.ListMessagesAsync("Inbox", query, 1000).ConfigureAwait(false);
// m6.Count == 532

Am I doing something wrong or is the maxNumberOfMessages parameter not working when building a query with DateComparisonType.ByDateTime? When I change the DateComparisonType to ByDate everything seems to work.

Could someone take a look at this issue?

Thanks
