重绘时输入值未更新

Question

正如您在测试中看到的那样，当视图重绘时，"p" 内容会更新，但不会更新与源具有相同数据流的输入值。为什么？

var root = document.body

let v = m.stream({
 field: m.stream()
})

var Hello = {
    view: function() {
        return m("main", [
            m("input", {
                value: v().field(),
                oninput: m.withAttr('value', v().field)
            }),
            m(
                'p', [
                    v().field()
                ]
            ),
            m(
                "button", {
                    "type": "button",
                    onclick: function() {
                        v({
                            field: m.stream()
                        })
                    }
                }, [
                    'save'
                ]
            ),
            m('div', ['Write on input then click save. After click save the P content disappear but input value still. why?'])
        ])
    }
}

m.mount(root, Hello)
