Summary0001939: Data Trigger in inline Window Style doesn't take effect
Description

In the main window for my application, if I set a window style that includes a data trigger, the data trigger does not happen, and appears to not be processed.

Steps To Reproduce

Test 1:



<Window>

<Window.Style>

<Style TargetType="{x:Type Window}">

<Style.Triggers>

<DataTrigger Binding="{Binding Path=Visibility, ElementName=ThatOtherTextBlock}" Value="Visible">

Result: No effect, no error messages printed. This is the main thing I want to do.

Test 2:



<Window.Style>

<Style TargetType="{x:Type Window}">

<Setter Property="Background" Value="Yellow"/>

Result: Background turns yellow. So I am setting the Style properly.

Test 3:



<Canvas>

<Canvas.Style>

<Style TargetType="{x:Type Canvas}">

<Style.Triggers>

<DataTrigger Binding="{Binding Path=Visibility, ElementName=ThatOtherTextBlock}" Value="Visible">

Result: This works properly. So my data trigger (and the stuff inside of it, which I'm not showing here) is correct.

Test 4:



<Window.Style>

<Style TargetType="{x:Type Window}">

<Style.Triggers>

<DataTrigger Binding="{Binding Path=Visibility, ElementName=DoesNotExist_asdfasdf}" Value="Visible">

Result: No effect. No error messages printed, including no error message about being unable to bind to that element name.
