NamedStateSpace does not propagate for discrete systems

[IJ1TI]

I have noticed that NamedStateSpace propagates differently depending on the system time domain for sensitivity and closed loop (T, complementary sensitivity) functions.

PS and CS are unaffected and still NamedStateSpace.

Example:

julia> typeof(P_analysis)
NamedStateSpace{Continuous, StateSpace{Continuous, Float64}}
julia> typeof(C_analysis)
NamedStateSpace{Continuous, StateSpace{Continuous, Float64}}
julia> S, PS, CS, T = gangoffour(P_analysis, C_analysis);
julia> typeof(S)
NamedStateSpace{Continuous, StateSpace{Continuous, Float64}}
julia> typeof(PS)
NamedStateSpace{Continuous, StateSpace{Continuous, Float64}}

julia> typeof(P_analysis)
NamedStateSpace{Discrete{Float64}, StateSpace{Discrete{Float64}, Float64}}
julia> typeof(C_analysis)
NamedStateSpace{Discrete{Float64}, StateSpace{Discrete{Float64}, Float64}}
julia> S, PS, CS, T = gangoffour(P_analysis, C_analysis);
julia> typeof(S)
StateSpace{Discrete{Float64}, Float64}
julia> typeof(PS)
NamedStateSpace{Discrete{Float64}, StateSpace{Discrete{Float64}, Float64}}

I can't reproduce this issue:

julia> typeof(gangoffour(P, C))
NTuple{4, NamedStateSpace{Discrete{Int64}, StateSpace{Discrete{Int64}, Float64}}}

EDIT: I've found the issue

What a speed!
