Issue with getAdvancedHistoryMessageList Returning Incorrect Messages When Fetching from Middle Position

Problem Description
When searching for a specific message and fetching surrounding messages, getAdvancedHistoryMessageList returns incorrect messages, while getAdvancedHistoryMessageListReverse returns correct results. Sequential fetching works fine.

Code Implementation

Future<List<Message>> getTargetMessageList({
  required String conversationID,
  Message? targetMessage,
}) async {
  if (targetMessage == null) return [];
  
  try {
    // Fetch messages before target message
    final beforeResult = await OpenIM.iMManager.messageManager.getAdvancedHistoryMessageList(
      conversationID: conversationID,
      startMsg: targetMessage,
      count: 10,
    );

    // Fetch messages after target message  
    final afterResult = await OpenIM.iMManager.messageManager.getAdvancedHistoryMessageListReverse(
      conversationID: conversationID,
      startMsg: targetMessage,
      count: 10,
    );
    
    return [
      ...beforeResult.messageList ?? [], 
      targetMessage, 
      ...afterResult.messageList ?? []
    ];
  } catch (e) {
    rethrow;
  }
}

Environment
Device: Android API 33, macOS
Version: 3.8.3-alpha.23
Behavior: Same issue occurs on both platforms
Current Status
✅ getAdvancedHistoryMessageListReverse: Returns correct messages
❌ getAdvancedHistoryMessageList: Returns incorrect messages when starting from middle position
✅ Sequential fetching: Works correctly
Expected Behavior
Both getAdvancedHistoryMessageList and getAdvancedHistoryMessageListReverse should return correct messages when fetching from a specific target message position.
