Why can't I use `onWithOptions` in elm 0.19

Elm 0.19 does not use elm-lang/html. You're reading the wrong documentation. It has been replaced by elm/html which has a custom function that serves the same purpose:

onClickNoBubble : msg -> Html.Attribute msg
onClickNoBubble message =
    Html.Events.custom "click" (Decode.succeed { message = message, stopPropagation = True, preventDefault = True })

I made a little helper function to get this to work.

onCustomClick : msg -> Html.Attribute msg
onCustomClick msg =
    custom "click"
        (Decode.succeed
            { message = msg
            , stopPropagation = True
            , preventDefault = True
            }
        )
