Vertex vexity is detected as "smooth" although it is clearly sharp and should be rather reported as "concave"

The test case is attached.

The problematic corner is detected to be "smooth" while it's apparently not. Vertex vexity is used in different feature recognition tools, including CNC features and cutting paths for sheet metals (also employed in DXF feature recognition). Therefore, this analysis needs to be perfect.
