Version

2.4.2

Reproduction link

Steps to reproduce

<div id="app">
  <div v-if="show">
    div1
  </div>
  <demo></demo>
  <div v-if="show">
    div2
  </div>
</div>

如上结构，show更新时会导致demo组件重新渲染

tips:sorry 上一个issue用错vue的版本，现在改成2.4.2版本也是有同样问题。

What is expected?

demo组件和v-if指令无关时不能刷新

What is actually happening?

show更新时会导致demo组件重新渲染
