数组simplediff为false,但数据引用变化时,会产生父子组件数据不一致

     const Component2 = Regular.extend({

         name: 'List',
         template: "<h1>{list1}</h1>",
         init() {

           setTimeout((function () {

             // 1. 实际也修改了parent.list对应的watcher里的last???
             this.data.list1[0] = 99
             // 2. 此时,Parent#list 值是 [] , 但是last变成了[99]。 深坑
             this.$update();
             expect(this.data.list1).to.eql([99]) // 实际是[]
             done()

           }).bind(this), 0);

         }
       });

       const Component = Regular.extend({

         name: 'Parent',

         template: `
                <List list1={list}/>
            `,
         config() {
           this.data.list = [];
           // this.data.list = [1]
         },
         init() {
           this.data.list = [];
           // this.data.list = [1] //同样会出错
           //  这个update 由于list并没有判断为改变,所以last还是原来的数组,此时List再修改就会导致出错
           this.$update();
         }
       });

       new Component().$inject('body');


     })
