Can you add some test cases for this change? Thanks

@chenjiahan 当然可以，不过我遇到一个错误，当badge为对象字面量时就会导致下面这个错误。如果badge为ref包裹的对象则没有这个问题。我目前正在解决这个，但进度不太理想，我可能要花一些时间。😞
最简单的办法就是不用对象的形式，就像和dot属性一样全都提取出来，但这样的话担心tab的属性会变得臃肿，你怎么认为？

<van-tabs>
  <van-tab :badge="{}" /> // Error: Maximum recursive updates exceeded in component <van-tabs>
</van-tabs>

<script>
const badge = ref({});
</script>

<template>
  <van-tabs>
    <van-tab :badge="badge" /> // No Error
  </van-tabs>
</template>

我在vue的练习场中复刻了这一行为：链接
我不确定这是否是Vue本身的问题，还是这种写法本就是不允许的。

看起来是循环触发渲染了，可能要加一些判断逻辑
