Fix 3D arrow glyphs in HSec Actor for bounding boxes (party) outside of the data field
For bounding boxes which are not completely inside the data field of the vector field variables, when drawing 3D arrow vector glyphs of the HSec Actor sometimes additional shadows of non existing arrows appear.
This phenomenon occurs especially when using the interaction mode and moving the cursor in the scene view widget.
It is more likely to occur when drawing many arrows.
