`let mutable private` used with JS import generate wrong JavaScript code

[MangelMaxime]

Description

open Fable.Core.JsInterop

type ToastrOptions =
    abstract Thing : string

[<RequireQualifiedAccess>]
module Toastr =
    let mutable private theOptions: ToastrOptions =
        //()
        import "options" "toastr"

import { options } from "toastr";

export const Toastr_theOptions = options;

Toastr_theOptions should not be a const (immutable) but a let.
