setAttribute being applied to parent

I have the following code

    div(classes = setOf("alert", "alert-dismissible")) {
                maxWidth = 20.rem
                button(text = "×", classes = setOf("close")) {
                    setAttribute("data-dismiss", "alert")
                }
            }
    }

which I’m expecting to add a data-dismiss attribute to the button, but is actually being applied to the parent div.

Is this correct behaviour? Is it possible to achieve without wrapping the button in another div?

Many Thanks.

I’ve commited support for custom attributes for the Component interface and the Widget class, so it will be available for all KVision components.

Sorry for the late answer but I had to earn some money for my life, and had little time for other things 😉 Now I’m getting ready for KVision and the new release will be very soon.
