Is there a breaking change in default value of props between Vue3 and Vue2?

[rudyxu1102]

const Comp = {
  props: {
    fooFn: {
      type: [Function, String],
      default() {
        return 'bar'
      }
    }
  },
  created() {
    // In Vue2
    console.log(this.fooFn); // function default() { return 'bar' }
    // In Vue3
    console.log(this.fooFn); // 'bar'
  }
}
