Sutil fails with Child not found when transitionning from Html.parse to a real SutilElement

[MangelMaxime]

type Reproduction =
    | Case1
    | Case2

let app () =
    let state = Store.make Reproduction.Case1

    Html.div [
        Bind.fragment
            state
            (fun state ->
                match state with
                | Reproduction.Case1 ->
                    Html.parse "This is case 1"

                | Reproduction.Case2 ->
                    Html.div [
                        Html.text "This is case 2"
                    ]
            )

        Html.button [
            Ev.onClick (fun _ -> Store.set state Reproduction.Case2)
            prop.text "Go to case 2"
        ]
    ]

My suspicion is that Html.parse does not create a child but set innerHtml or something like that. I think the access to child in the replaceChild function should be protected.
