van-dialog组件包含van-field的情况ios如何自动聚焦？

[peiGod]

<template>
  <van-dialog v-model:show="isDialogVisible" @opened="onDialogOpened" show-cancel-button>
    <van-field ref="inputRef" tabindex="0" v-model="inputValue" placeholder="请输入内容" />
  </van-dialog>
  <van-button type="primary" @click="showDialogWithFocus">弹出并自动聚焦</van-button>
</template>

<script>
import { ref, nextTick } from 'vue';

export default {
  setup() {
    const isDialogVisible= ref(false);
    const inputValue = ref('');
    const inputRef = ref(null);

    const showDialogWithFocus= () => {
      isDialogVisible.value = true;
      nextTick(() => {
        // inputRef.value?.focus();
      });
    };

    const onDialogOpened= () => {
        nextTick(() => {
          inputRef.value?.focus();
        });
      };
    return { isDialogVisible, inputValue, inputRef, showDialogWithFocus, onDialogOpened};
  },
};
</script>

如上实例代码：
1、在showDialogWithFocus触发dialog组件显示时，nextTick调用focus，均不可自动聚焦
2、在opened回调事件中，nextTick调用focus，安卓可自动聚焦，ios不行
