WPF video view is "invisible" when HorizontalAlignment and/or VerticalAlignment properties are set.

If I try to center my video object within a container (Grid, StackPanel, etc...) by performing the following:

<vlc:VideoView Grid.Column="0" Grid.Row="0" HorizontalAlignment="Center" VerticalAlignment="Center" x:Name="vlcPlayer" Panel.ZIndex="1"/>

the video object is invisible. I can hear the audio of the video playing, but no video is ever shown. In order to make the video appear again, I have to remove the alignment properties.

Is this a known issue, or future feature option?
