【报Bug】报一个关于uni-file-picker组件的BUG

示例代码：

<uni-file-picker limit="5" :sourceType="sourceType" title="最多选择5张图片"  
                                @delete="(e) => deleteimage(e,index)" @select="(e) => handleChange(e, index)"  
                                v-model="item.pictureUrlList"></uni-file-picker>

deleteimage(e, type) {  
                for (var i = 0; i < this.executeDtoList[0].executeParamList[type].pictureUrlList.length; i++) {  
                    if (e.index === i) {  
                        this.executeDtoList[0].executeParamList[type].pictureUrlList.splice(i, 1);  
                        console.log(this.executeDtoList[0].executeParamList)  
                    }  
                }  
            },

操作步骤：

<uni-file-picker limit="5" :sourceType="sourceType" title="最多选择5张图片"  
                                @delete="(e) => deleteimage(e,index)" @select="(e) => handleChange(e, index)"  
                                v-model="item.pictureUrlList"></uni-file-picker>

deleteimage(e, type) {  
                for (var i = 0; i < this.executeDtoList[0].executeParamList[type].pictureUrlList.length; i++) {  
                    if (e.index === i) {  
                        this.executeDtoList[0].executeParamList[type].pictureUrlList.splice(i, 1);  
                        console.log(this.executeDtoList[0].executeParamList)  
                    }  
                }  
            },
