Boolean Difference/Exclude operation got broken

If I create a boolean Difference/Exclude operation on 2 shapes the intersecting part is still visible, however it should not be.

(f I observed correctly the point and segment data is generated correctly for the result, but the display is still wrong.)

Reproduce the Boolean Difference/Exclude operation on two overlapping shapes using the attached example, then trace the display path for the generated result. Compare the rendered output with the point and segment data, and consider the issue done when the intersecting portion is no longer visible while the result geometry remains correct.
