Comment(by SimonKing):
There is a new singular spkg at #8059. However, this does not solve the
problem. The only difference is that now one has
{{{
sage: I.groebner_basis(algorithm='toy:buchberger2')
[2*x^2 + x*y, 3*x*y, 2*y^2]
}}}
Hence, the result is reduced (the first bug is gone), but still wrong.
