Can not disable the trackball marker for specific series in Cartesian charts

[furuyan]

Bug description

I want to disable the trackball marker for specific series in Cartesian charts,
and I implemented code based on this reference.
https://support.syncfusion.com/kb/article/10485/how-to-disable-the-trackball-marker-for-specific-series-in-cartesian-charts

It worked fine in syncfusion_flutter_charts 24.1.46, but in 25.2.5, TrackballMarker is now showing up in all Series.

Steps to reproduce

1. Drag the chart

Code sample

Code sample

class _MyHomePageState extends State<_MyHomePage> {
  late TrackballBehavior _trackballBehavior;
  @override
  void initState() {
    _trackballBehavior = TrackballBehavior(
        enable: true,
        activationMode: ActivationMode.singleTap,
        shouldAlwaysShow: true,
        builder: (BuildContext context, TrackballDetails trackballDetails) {
            return Container(
              padding: const EdgeInsets.all(3.0),
              decoration: BoxDecoration(
                  border: Border.all(color: Colors.black)
              ),
              child: Text("Custom Tooltip"),
            );
        },
        markerSettings: TrackballMarkerSettings(
          markerVisibility: TrackballVisibilityMode.auto,
        ));
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
        backgroundColor: Colors.grey,
        appBar: AppBar(
          title: const Text('Syncfusion Flutter chart'),
        ),
        body: Center(
          child: Container(
            height: 500,
            width: 340,
            child: SfCartesianChart(
                backgroundColor: Colors.white,
                primaryXAxis: CategoryAxis(),
                trackballBehavior: _trackballBehavior,
                series: <LineSeries<_SalesData, String>>[
                  LineSeries<_SalesData, String>(
                      dataSource: <_SalesData>[
                        _SalesData('Jan', 35),
                        _SalesData('Feb', 28),
                        _SalesData('Mar', 34),
                        _SalesData('Apr', 32),
                        _SalesData('May', 40)
                      ],
                      xValueMapper: (_SalesData sales, _) => sales.year,
                      yValueMapper: (_SalesData sales, _) => sales.sales,
                      markerSettings:
                          MarkerSettings(isVisible: true, width: 0, height: 0)),
                  LineSeries<_SalesData, String>(
                      dataSource: <_SalesData>[
                        _SalesData('Jan', 15),
                        _SalesData('Feb', 8),
                        _SalesData('Mar', 14),
                        _SalesData('Apr', 12),
                        _SalesData('May', 20)
                      ],
                      xValueMapper: (_SalesData sales, _) => sales.year,
                      yValueMapper: (_SalesData sales, _) => sales.sales,
                      markerSettings: MarkerSettings(
                          isVisible:
                              false // Setting false to this series to not to render marker for this series.
                          ))
                ]),
          ),
        ));
  }
}

class _SalesData {
  _SalesData(this.year, this.sales);

  final String year;
  final double sales;
}
