Created Issue: SeriesDefinition Visibility does nothing [10539]

Changing the Visibility property on the SeriesDefinition does nothing to the look of the chart, when I would have expected it to show/collapse the appropriate series.

<toolkit:StackedColumnSeries>
<toolkit:SeriesDefinition
Title="Series A"
ItemsSource="{Binding ...}"
IndependentValueBinding="{Binding ...}"
DependentValueBinding="{Binding ...}"
Visibility="Collapsed"/>
</toolkit:StackedColumnSeries>
