不太优雅的方式临时解决这个bug

const searchValue = ref<string>('');
function change() {
  // 改变searchValue的值，触发监听方法清空InputValue和targetValue
  searchValue.value = ' ';
  nextTick(() => {
    searchValue.value = '';
  });
}

<Select
  :search-value="searchValue"
  :token-separators="[',', '\n']"
  mode="tags"
  @change="change"
/>
