Cannot set CustomAttribute to nested erasable type

Description

Cannot set CustomAttribute to nested erasable type
CustomAttribute with Generative types work fine

Repro steps

Add nested type with custom attributes

    let createType typeName (count:int) =
        let myType = ProvidedTypeDefinition(asm, ns, typeName, Some typeof<obj>, isErased = true)
        let ctor = ProvidedConstructor([], invokeCode = fun args -> <@@ ():> obj @@>)
        myType.AddMember(ctor)

        let nestedType = ProvidedTypeDefinition("Nested", Some typeof<obj>)
        let attr = {
            new Reflection.CustomAttributeData() with
            member __.Constructor = (typeof<MyNamespace.MyAttribute>).GetConstructor([|typeof<string>|])
            member __.ConstructorArguments = [|"1"|] |> Array.map (fun i -> CustomAttributeTypedArgument(i.GetType(), i)) :> _
            member __.NamedArguments = [||] :> _
        }
        nestedType.AddCustomAttribute(attr)
        myType.AddMember nestedType

displaying a list of attributes in debug script

type B = LemonadeProvider.ErasingProvider<1>
let t2 = typeof<B.Nested>
t2.CustomAttributes |> Seq.iter(fun a -> printfn "%A" a )

Expected behavior

[MyNamespace.MyAttribute("1")]

Actual behavior

[System.SerializableAttribute()]
[System.Runtime.CompilerServices.TypeForwardedFromAttribute("mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089")]
[System.Runtime.InteropServices.ComVisibleAttribute((Boolean)True)]
[System.Runtime.InteropServices.ClassInterfaceAttribute((System.Runtime.InteropServices.ClassInterfaceType)1)]
[System.Runtime.CompilerServices.NullableContextAttribute((Byte)2)]
