How to restrict the Connector's source and target decorator from being positioned in different places in WPF Diagram (SfDiagram)?

In the WPF Diagram, you can restrict the connector’s TargetDecorator and SourceDecorator from being positioned in different places by setting the Stretch property to Fill in the TargetDecoratorStyle and SourceDecoratorStyle property of the Connector. Here’s a code example to demonstrate how to achieve this.

XAML Code Snippet:

<!--Style for the Connector-->
<Style TargetType="syncfusion:Connector">
   <Setter Property="ConnectorGeometryStyle">
       <Setter.Value>
           <Style TargetType="Path">
               <Setter Property="Stroke" Value="#6BA5D7"/>
               <Setter Property="StrokeThickness" Value="1"/>
           </Style>
       </Setter.Value>
   </Setter>
   <Setter Property="TargetDecoratorStyle">
       <Setter.Value>
           <Style TargetType="Path">
               <Setter Property="Fill" Value="#6BA5D7"/>
               <Setter Property="StrokeThickness" Value="1"/>
               <!-- Set the Stretch property to fill-->
               <Setter Property="Stretch" Value="Fill"/>
           </Style>
       </Setter.Value>
   </Setter>
   <Setter Property="SourceDecoratorStyle">
       <Setter.Value>
           <Style TargetType="Path">
               <Setter Property="Fill" Value="#6BA5D7"/>
               <Setter Property="StrokeThickness" Value="1"/>
               <!-- Set the Stretch property to fill-->
               <Setter Property="Stretch" Value="Fill"/>
           </Style>
       </Setter.Value>
   </Setter>
</Style>
