ThreadGroup line 273 cloneTree(threadGroupTree)，I have setted CSVDataSet with filename，but after cloneTree，my filename was lost

Expected behavior

I hope cloneTree will not lost data in threadGroupTree

Actual behavior

after cloneTree, my data has lost

Steps to reproduce the problem

// 创建一个CSV Data Set Config元件 CSVDataSet csvDataSet = new CSVDataSet(); csvDataSet.setFilename("D:\work\user.csv"); // CSV文件路径 csvDataSet.setVariableNames("username,password"); // CSV文件中的列名 csvDataSet.setDelimiter(","); // CSV文件的分隔符

    // 创建一个 LoopController
    LoopController loopController = new LoopController();
    loopController.setLoops(1);  // 设置循环次数
    loopController.initialize();

    ThreadGroup threadGroup = new ThreadGroup();
    threadGroup.setNumThreads(1);
    threadGroup.setRampUp(0);
    threadGroup.setSamplerController(loopController);

    // 创建一个TestPlan
    TestPlan testPlan = new TestPlan("My Test Plan");

        // 创建一个HashTree来保存TestPlan
        ListedHashTree loginPlanTree = new ListedHashTree();
        ListedHashTree threadGroupHashTree = (ListedHashTree) loginPlanTree.add(testPlan, threadGroup);
        threadGroupHashTree.add(cookieManager);
        threadGroupHashTree.add(csvDataSet);
