移动端输入框做清空聚焦操作时，内容没有清空且文本有下划线，是什么问题，如何解决？

Question

组件库用的是nutui-uniapp，扫描用的是uni.scanCode，验证失败和点击清空都会出现这种情况

<template>
  <page-container>
    <template #search>
      <nut-form>
        <nut-form-item label="点位条码">
          <scan-code
            v-model="queryParams.pointCode"
            placeholder="请扫描点位条码"
            v-model:autofocus="pageData.pointFocus"
            :disabled="pageData.pointCodeDisabled"
            @blurEvent="validatePointCode"
          ></scan-code>
        </nut-form-item>
      </nut-form>
    </template>
    <template #bottom>
      <nut-button style="width: 48%" shape="square" type="danger" @click="handleCancel">
        清 空
      </nut-button>
    </template>
  </page-container>
</template>

<script setup lang="ts">
import { reactive } from 'vue';
import { queryPointBarcode } from '@/api/wms/container-point/index';

const initQueryValues = () => ({
  pointCode: '',
  containerCode: '',
});

const initPageValues = () => ({
  pointFocus: true,
  containerFocus: false,
  pointCodeDisabled: false,
  pointType: '',
  maxContainerQty: 0,
});

// 查询
const queryParams = reactive(initQueryValues());
// 页面
const pageData = reactive(initPageValues());

// 扫描点位条码
const validatePointCode = async () => {
  if (!queryParams.pointCode) return;
  uni.showLoading({
    title: '加载中',
  });
  const { success } = await queryPointBarcode({
    pointCode: queryParams.pointCode,
  });
  uni.hideLoading();
  if (success) {
    pageData.pointCodeDisabled = true;
    pageData.containerFocus = true;
  } else {
    queryParams.pointCode = '';
    pageData.pointFocus = true;
  }
};

// 清空按钮
const handleCancel = () => {
  pageData.pointCodeDisabled = false;
  setTimeout(() => {
    Object.assign(queryParams, initQueryValues());
    Object.assign(pageData, initPageValues());
  }, 100);
};
</script>

下面是组件的部分代码

<template>
  <view class="scan-container">
    <nut-input
      v-model="currentValue"
      @update:model-value="updateValue"
      v-bind="$attrs"
      :autofocus="focus"
      @blur="blurEvent"
    >
      <template #right>
        <nut-icon :name="props.scanIcon" :size="props.iconSize" @click="handleScanIcon"></nut-icon>
      </template>
    </nut-input>
  </view>
</template>

<script setup lang="ts">
import { ref, watchEffect } from 'vue';

type Props = {
  modelValue?: string;
  scanIcon?: string;
  scanType?: Array<any>;
  autofocus: boolean;
  iconSize?: number | string;
};

const props = withDefaults(defineProps<Props>(), {
  autofocus: false,
  scanIcon: 'scan2',
  scanType: () => ['qrCode', 'barCode'],
});

const emit = defineEmits(['update:modelValue', 'blurEvent', 'update:autofocus']);

const currentValue = ref(props.modelValue);
const focus = ref(props.autofocus);

const updateValue = (e: any) => {
  emit('update:modelValue', e);
};

watchEffect(() => {
  currentValue.value = props.modelValue;
  focus.value = props.autofocus;
});

const handleScanIcon = () => {
  uni.scanCode({
    onlyFromCamera: false,
    scanType: props.scanType,
    success: ({ result }) => {
      currentValue.value = result;
      updateValue(result);
      blurEvent(result);
    },
  });
};

const blurEvent = async (val: any) => {
  if (val) {
    setTimeout(() => {
      emit('blurEvent');
      emit('update:autofocus', false);
    }, 500);
  }
};
</script>
