Elements remain in the DOM after updating chart data

After updating the chart data, some elements remain in the DOM. This can clutter the browser if the data updates come in on intervals and the chart remains in operation for a while. A screenshot is attached below.

MCVE:

@using Telerik.Blazor
@using Telerik.Blazor.Components.Button
@using Telerik.Blazor.Components.Chart
 
<h3>Chart</h3>
 
 
<TelerikButton Primary="true" @onclick="AddDataPoint">Add data point</TelerikButton>
 
<TelerikChart Transitions="false">
    <TelerikChartSeriesItems>
        <TelerikChartSeries Type="ChartSeriesType.Line" Name="CPU Usage Data" Data="@simpleData">
        </TelerikChartSeries>
    </TelerikChartSeriesItems>
 
    <TelerikChartValueAxes>
        <TelerikChartValueAxis Max="100" Color="black"></TelerikChartValueAxis>
    </TelerikChartValueAxes>
 
    <TelerikChartTitle Text="CPU Usage"></TelerikChartTitle>
 
    <TelerikChartLegend Position="Telerik.Blazor.ChartLegendPosition.Bottom">
    </TelerikChartLegend>
</TelerikChart>
 
 
 
@code {
    void AddDataPoint()
    {
        Random random = new Random();
        var _val = Math.Round((random.NextDouble() * 100), 3);
 
        if (simpleData.Count >= 60)
        {
            simpleData = simpleData.TakeLast(59).ToList();
        }
        simpleData.Add(_val);
 
        //StateHasChanged();
 
    }
 
    public List<object> simpleData = new List<object>();
}
