SCC does not transfer residuals to solution object

[mx-p9a]

Describe the bug 🐞

When using the SCC algorithm to solve a ModelingToolkit initialization system, the residuals are not transferred to the solution object.

julia> iprob = InitializationProblem(sys, 0.0, u0, guesses = guesses(sys))
SCCNonlinearProblem with uType Vector{Float64}. In-place: false
u0: 6-element Vector{Float64}:
 0.0
 0.0
 0.0
 0.0
 0.0
 0.0

julia> isol.alg
SCCNonlinearSolve.SCCAlg{Nothing, Nothing}(nothing, nothing)

julia> isol.retcode
ReturnCode.Success = 1

julia> isol.resid
5-element Vector{Nothing}:
 nothing
 nothing
 nothing
 nothing
 nothing

julia> isol.stats

julia>

Expected behavior
