Xaml binding error: VerticalAlignment

Hi.

It's not a big deal, but I would like to fix these Xaml binding errors:

They occur both in my tool and in the example. Any idea how to fix this?

I think I found out the root couse of this problem. Seems like this control template triggers are leading to binding issues:

<ControlTemplate.Triggers>
    <DataTrigger Binding="{Binding VerticalAlignment, RelativeSource={RelativeSource AncestorType=sdl:MultiSelectComboBox}}" Value="Stretch">
        <Setter TargetName="PART_MultiSelectComboBox" Property="MaxHeight" Value="{Binding ActualHeight, RelativeSource={RelativeSource AncestorType=sdl:MultiSelectComboBox}}"/>
    </DataTrigger>
</ControlTemplate.Triggers>

and

<ControlTemplate.Triggers>
    <DataTrigger Binding="{Binding VerticalAlignment, RelativeSource={RelativeSource AncestorType=generic:MultiSelectComboBox}}" Value="Stretch">
        <Setter TargetName="PART_MultiSelectComboBox" Property="MaxHeight" Value="{Binding ActualHeight, RelativeSource={RelativeSource AncestorType=generic:MultiSelectComboBox}}" />
    </DataTrigger>
</ControlTemplate.Triggers>

AI is proposing to replace this piece of code with

<ControlTemplate.Triggers>
    <DataTrigger Binding="{Binding VerticalAlignment, RelativeSource={RelativeSource TemplatedParent}}" Value="Stretch">
        <Setter TargetName="PART_MultiSelectComboBox"
                Property="MaxHeight"
                Value="{Binding ActualHeight, RelativeSource={RelativeSource TemplatedParent}}" />
    </DataTrigger>
</ControlTemplate.Triggers> 

As far as I can tell it worked as expected.
