Error when converting TensorProductOperator to sparse matrix

[cvsvensson]

Converting a TensorProductOperator to a sparse matrix results in an error.

using SparseArrays, SciMLOperators
m = MatrixOperator(rand(1,1))
M = kron(m,m)
sparse(M)
#MethodError: no method matching sparse(::Type{AbstractMatrix}, ::MatrixOperator{Float64, Matrix{Float64}

This happens at

SciMLOperators.jl/ext/SciMLOperatorsSparseArraysExt.jl

Lines 13 to 15 in 4a633c7

	function SparseArrays.sparse(L::SciMLOperators.TensorProductOperator)
	return LinearAlgebra.kron(sparse.(AbstractMatrix, L.ops)...)
	end

in SciMLOperators v1.16.0. It seems to me that the argument AbstractMatrix should not be there.
