Summary0002054: Binding to ActualWidth property returns 0 at runtime
Description

I was trying to bind a grids width property to its child elements ActualWidth to control size. But it is always set to 0, even tho the actual width of the child is correct in the inspector.
This solution works fine in WPF, but breaks in Unity.

As described in my forum post: https://www.noesisengine.com/forums/viewtopic.php?f=3&t=2346&p=12942#p12942

Steps To Reproduce

The issue should always happen with this code:

<DockPanel>
<Control Template="{StaticResource IconPlus}" Width="120" Height="120" DockPanel.Dock="Left" Panel.ZIndex="1" />
<Control Template="{StaticResource IconCoin}" Width="120" Height="120" DockPanel.Dock="Right" Panel.ZIndex="1" />
<Grid Width="{Binding Path=ActualWidth, ElementName=CoinsAmount, UpdateSourceTrigger=PropertyChanged}">
<Control Template="{StaticResource DarkPanelBackground}" Margin="-45, 40, -60, 40" />
<TextBlock x:Name="CoinsAmount" Text="8 547" FontSize="36" VerticalAlignment="Center" HorizontalAlignment="Center" Foreground="White" />
</Grid>
</DockPanel>
