Delete including Top condition does not work

[Mortimer76]

The following linq statement

 (
     from messageEvent in s.Query<MessageEventDTO>()
      join msg in s.GetTable<MessageDTO>() on messageEvent.MessageName equals msg.Name
     where (messageEvent.TimestampConfirmed < olderThan &&
          (messageEvent.TimestampGone < olderThan || msg.MessageType != MessageType.OnlyOnceLeaving))
     select messageEvent
).Take(maxDeleteCountPerCommand).Delete(); 

is converted to the sql statement

DELETE [messageEvent]
FROM
    [Common_MessageSystem_Events] [messageEvent]
        INNER JOIN [Common_MessageSystem_Messages] [msg] ON [messageEvent].[MessageName] = [msg].[Name]
WHERE
    [messageEvent].[TimestampConfirmed] < @p1 AND ([messageEvent].[TimestampGone] < @p2 OR [msg].[MessageType] <> 20)

so the Top / Take condition is not considered.
