Dial's stepSize handling is broken

import QtQuick 2.6
import QtQuick.Controls 2.0

ApplicationWindow {
    width: 360
    height: 360
    visible: true

    Dial {
        from: 10
        to: 100
        stepSize: 10
        snapMode: Dial.SnapAlways
        onValueChanged: console.log("Value is", value)
    }
}
