When printing a Blazor WASM Pie Chart, it looses all colors associated with it. Attached are pictures before and after printing and the javascript used for printing along with my markup.
Before print:
beforeprint
After print:
afterprint
Javascript:

function printChartAreaDiv() {
    var divContents = document.getElementById("chartPrintArea").innerHTML;
    var a = window.open('', '', 'height=500, width=500');
    a.document.write('<html>');
    a.document.write('<body > <br>');
    a.document.write(divContents);
    a.document.write('</body></html>');
    a.document.close();
    a.print();
}

Markup being printed that contains the piechart:

<div id="chartPrintArea" class="row">
            <PieChartComponent @ref="chart"
                           ReportObjectId=@ReportObject.Id
                           StartTime=@_startTime.Value
                           EndTime=@_endTime.Value />
    </div>

PieChartComponent:

@if (_loading)
{
    <Chase style="margin-top:75px" Center="true" />
}
else
{
    <RadzenChart>
        <RadzenPieSeries Data="@_values" CategoryProperty="Name" Title=@_reportObject.Title
                     ValueProperty="Value" />
    </RadzenChart>
}

You are only copying the HTML of the chart but it also uses CSS. Try including the Radzen.Blazor theme CSS file as well.
