[Gmsh] possible bug in the Frontal Algo

I am wondering about possible reasons for the missing of some corner triangles in meshes generated by the Frontal Algo.

A cornar triangle is a triangle that has two edges on the face contour.

The vertex of this triangle which is shared by the two contour edges does not belong to any other triangle (of the same face).

Is it possible that, when the corner triangle becomes the worst and gets deleted by the function bowyerWatsonFrontal, the corner vertex
is also removed (because no other face triangle uses it) and is never restored ?
