Issue setting foreground color of TextBox via ChangePropertyAction

I try to set the Foreground property of a TextBox via a DataTriggerBehavior and ChangePropertyAction:

<TextBox Name="LastName" Text="{Binding Person.LastName}"> <i:Interaction.Behaviors> <ia:DataTriggerBehavior Binding="{Binding Person.LastName, Converter={StaticResource toLowerStringConverter}}" ComparisonCondition="Equal" Value="schulz"> <ia:ChangePropertyAction TargetObject="{Binding #LastName}" PropertyName="Foreground" Value="#FF0000" /> </ia:DataTriggerBehavior> </i:Interaction.Behaviors> </TextBox>

But the TextBox doesnt show the letters at all, although you can see that it has content because you can see some “spaces” inside the TextBox:

I attached an example solution. AvaloniaTest.zip

I am using the latest version 0.9.12

@MopsiMauser Found the issue and fixed. The fixed version will be released today as 0.10.0-preview5 and will be part of 0.10.0 later.
