Display parametric types in a better way?

Consider the following two functions in module CGP.

"""
$(TYPEDSIGNATURES)
"""
function fun1(x::AbstractVector{<:Real})
end


"""
$(TYPEDSIGNATURES)
"""
function fun2(x::AbstractVector{T}) where T<:Real
end

The following documentation is produced.

I noticed two issues.

1. The AbstractVector in fun2 becomes AbstractArray again even if I am using Julia 1.6.0. (See #108)
2. In fun1, the implicit type parameter is an ugly var"#s2". Is it possible to just show the original form x::AbstractVector{<:Real}?

Start by reproducing the documentation output for the CGP module examples fun1 and fun2 using Julia 1.6.0, then trace the DocStringExtensions signature-rendering entry point involved in TYPEDSIGNATURES. Done means the parametric signatures retain AbstractVector and present the implicit bound without the generated var"#s2" name.
