Cant simplify electrical units as expected (S*Ω)

Hi all, I hope this is not a repeat question.

I am trying to do an operation equivalent to this, but it does not work:
`uconvert(u"1/km", 1.0u"S" * 1.0u"Ω" * 1.0u"1/km")`

> MethodError: no method matching uconvert(::Unitful.Quantity{Int64, 𝐋^-1, Unitful.FreeUnits{(km^-1,), 𝐋^-1, nothing}}, ::Unitful.Quantity{Float64, 𝐋^-1, Unitful.FreeUnits{(km^-1, Ω, S), 𝐋^-1, nothing}})

However, similar situations where units cancel each other out work just fine:
`uconvert(u"Ω/km",1.0*u"1/km" * 1.0u"V"/1.0u"A")`

> 1.0 Ω km^-1

Is this a bug or am I misunderstanding what this package can do? Should I be using a different function?

Thanks!

Start by reproducing both uconvert examples from the issue in Unitful.jl and compare how S*Ω is represented with the V/A expression. No file or test is named; done means establishing whether the differing simplification is a bug or supported usage and identifying the relevant implementation or test location.
