Bug Description
Mesh refinement breaks on some occasions and gives meshes with hanging nodes. This happens both using bisection (Rivara) refinement and regular cut refinement close to a reentrant corner.
The hanging nodes appear when the mesh is heavily refined only in the vicinity of the corner (which appears more often using either Dorfler marking or fixed fraction refinement with a small refinement fraction).
Test case is a 2D mesh (channel_with_flap) present in the cbc.solve repository.
