Description
I am trying to construct a 3D tensor product with Ultraspherical polynomials, and I try this doing:
using ClassicalOrthogonalPolynomials
P=Ultraspherical(-0.5)
N=100
P1=plan_transform(P,(N,N,N))
but I got an error that says:
ERROR: MethodError: no method matching plan_th_ultra2ultra!(::Type{Float64}, ::Tuple{Int64, Int64, Int64}, ::Float64, ::Float64)
The function `plan_th_ultra2ultra!` exists, but no method is defined for this combination of argument types.

Research direction
Reproduce the issue with the provided Julia snippet, then trace plan_transform for the 3D Ultraspherical case to the reported plan_th_ultra2ultra! entry point. Done means the 3D tensor-product call constructs successfully without the reported MethodError.
