SciChartLegend Binding Issue

Hi

I recently updated my SciChart license previously was using 6.3.0 but now using 8.3.0. Without changing any code other than the SetRuntimeLicenseKey I noticed a bunch of binding errors.

Warning 4 null Foreground TextBlock.Foreground Brush Cannot find source: RelativeSource FindAncestor, AncestorType=’SciChart.Charting.Visuals.RenderableSeries.LegendPlaceholder’, AncestorLevel=’1′.

Code below:

<SciChart:SciChartLegend
HorizontalAlignment="Left"
VerticalAlignment="Top"
LegendData="{Binding LegendData, ElementName=mainLegend}"
ShowVisibilityCheckboxes="True">
<SciChart:SciChartLegend.ItemsPanel>
    <ItemsPanelTemplate>
        <WrapPanel ItemWidth="150" Orientation="Horizontal" />
    </ItemsPanelTemplate>
</SciChart:SciChartLegend.ItemsPanel>

Searching for same problem I noticed someone else had exactly the same issue with an earlier version. This was addressed at the time with an update. Wondered if the issue had creeped back in?
