Hi, I wanted to solve a Algebraic equation in matrix form that looks like:
 = PolynomialRing(QQ, ["x", "y"])
I = Ideal(R, x, y)
M = Singular.Matrix(I)
typeof(M)
```
But the ty…

The flint library has a builtin type for rational matrices: `fmpq_mat_t`. This ticket proposes to replace the current array of `mpq_t` wrapped by `Matrix_rational_dense` in favor of `fmpq_mat_t`.

In #11900, some regressions were fixed that have been introduced in #9138. It seems that one of the examples from #11900 shows a regression again:
