If during decimation edge collapse of a tiny edge (special mode for degeneration fixing) failed because of appearance of multiple edges, test whether left or right triangle contains single 3-degree vertex inside, then collapse it instead ignoring error introduced and other violations (e.g. normal flip).
A test added where new behavior helps resolving many degenerations.
