accessibility - ios中的画外音和android中的对讲无法访问输入元素

Question

ios 中的画外音和 android 中的对讲在双击按钮时无法访问输入元素。在使用 tabindex="0" 作为输入元素时，它可以通过双击访问但仍然无法访问。还有一种方法可以在桌面上测试画外音或对讲。

  type="button"
  id="Pivot12-Tab1"
  class="ms-Button ms-Button--action ms-Button--command ms-Pivot-link link-221"
  role="tab"
  aria-selected="false"
  name="Search"
  data-content="Search"
  data-is-focusable="true"
  tabindex="0"
>
  <span
    class="ms-Button-flexContainer flexContainer-217"
    data-automationid="splitbuttonprimary"
  >
    <div class="ms-SearchBox root-222">
      <div
        class="ms-SearchBox-iconContainer iconContainer-223"
        aria-hidden="true"
      >
        <i
          data-icon-name="Search"
          aria-hidden="true"
          class="ms-SearchBox-icon icon-228"
          >&lt;/i
        >
      </div>
      <input
        id="SearchBox20"
        class="ms-SearchBox-field field-226"
        placeholder="Search by job title or ID"
        role="searchbox"
        aria-label="Search by job title or ID"
        value=""
        tabindex="-1"
      />
    </div>
  </span>
</button>
