Rational diagonal sparse matrix division reports `integer division error`

[eschnett]

This fails with a ERROR: DivideError: integer division error:

B = Diagonal(sparsevec([1],[1//1]))
W = Diagonal([1//1])
B / W

The expression is somewhat complicated, combining rational numbers, sparse vectors, and diagonal matrices, but it is well-defined. There should be no error.

The expression B * inv(W), which is mathematically identical, does not fail.
