How to prevent the Connector lines from overlapping the Connector's target decorator in WPF Diagram(SfDiagram)?

In the WPF Diagram, when the TargetDecorator of a Connector is set to a shape like “ClosedASME,” sometimes it may appear to overlap the connector segment. A simple way to resolve this is by reducing the size of the TargetDecorator using the TargetDecoratorStyle property. Below is an example demonstrating how to configure this in XAML:

XAML Code Snippet:

<!--Set the TargetDecorator shape to "ClosedASME"-->
<Setter Property="TargetDecorator" Value="{StaticResource ClosedASME}"/>

<!--Style for the Connectors TargetDecorator-->
<Setter Property="TargetDecoratorStyle">
    <Setter.Value>
        <Style TargetType="Path">
            <!-- Reduce the Width-->
            <Setter Property="Width" Value="15"/>
            <Setter Property="Fill" Value="#6BA5D7"/>
            <Setter Property="StrokeThickness" Value="1"/>
            <Setter Property="Stretch" Value="Fill"/> 
        </Style>
    </Setter.Value>
</Setter> 

Another way to resolve this issue is by using a different TargetDecorator shape instead of “ClosedASME.” For example, you can use “ClosedSharp”.

XAML Code Snippet:

<!--Set the TargetDecorator shape to "ClosedSharp"-->
<Setter Property="TargetDecorator" Value="{StaticResource ClosedSharp}"/>

<!--Style for the Connectors TargetDecorator-->
<Setter Property="TargetDecoratorStyle">
   <Setter.Value>
       <Style TargetType="Path">
           <Setter Property="Fill" Value="#6BA5D7"/>
           <Setter Property="StrokeThickness" Value="1"/>
           <Setter Property="Stretch" Value="Fill"/>
       </Style>
   </Setter.Value>
</Setter>
