Vue中ElementUI结合transform使用时如何修复el-select弹框定位不准确问题

<el-select
	ref="elSelect"
	placeholder="商机状态"
	size="small"
	v-model="proStage"
	:popper-append-to-body="false"
	@focus="focusFixDateSelectPosition"
	>
	<el-option
		v-for="item in stageList"
		key="item.FieldValue"
		label="item.FieldLabel"
		value="item.FieldValue"
		>
	</el-option>
</el-select>

/**
* 解决Select定位问题
*/
focusFixDateSelectPosition(){
	let e = this.$refs['elSelect'].$refs['popper'];
	console.log('e', e);
}

/**
 * 回调函数
 */
const selectCallback = e => {
  setTimeout(() => {
    if('undefined'===typeof e['popperJS'] || null == e['popperJS']){
      selectCallback(e);
    }else{
      e.popperJS.state.position = 'absolute';
      e.popperJS.update();
      setTimeout(() => {
         e.$el.style.top = 'inherit';
         e.$el.style.left = '0';
       }, 20);
    }
  }, 20);
}

focusFixDateSelectPosition(eve){
    let e = this.$refs['elSelect'].$refs['popper'];
    selectCallback(e);
}
