How can I make products with (constant) sparse boolean matrices and vectors work with Zygote? Example:

```
julia> using Zygote, SparseArrays, LinearAlgebra
julia> gradient(v -> dot(sparse([true;false]),v), [1.;0.])

I did not expect issues because this is just a constant used as a bit mask. The same product works if I change the matrix type to `Int64`
