Walkthrough本次修改将 ChangesTablist 无障碍归属
Estimated code review effort: 2 (简单) | ~10 分钟 Merge Risk: 🟡 Moderate · up to The accessibility fix is incomplete because editable tabs still place the add button inside the tablist, which may continue to cause accessibility validation errors. Merge should wait until the button is outside the tablist or its intended semantics are explicitly validated. Suggested reviewers: Poem

Closing as a duplicate of #1015. Once the repository-wide overlap search became available again, I confirmed that #1015 already keeps tabBarExtraContent, add/remove, and overflow controls outside the tablist and includes broader SSR, empty-list, layout, and axe coverage. I had already reviewed and approved that exact head, so #1018 adds no independent value. Sorry for the duplicate. |

将 AddButton 移出 role="tablist" 的可访问性所有权。
当 editable 开启且 hasDropdown 为 false 时，Line 622 的 AddButton 仍渲染在这个 role="tablist" 容器内。Line 629 只在有隐藏标签时设置 visibility: hidden，所以正常的可编辑场景仍会把 add control 暴露为 tablist 的后代。这不满足“tablist 只拥有 role="tab" 元素”的要求，并可能继续触发 aria-required-children 检查。
请保留现有布局、tabListRef 尺寸计算和 overflow 行为，但将内层 AddButton 放到 tablist 的同级容器。同时在 tests/index.test.tsx 增加 editable 场景，断言该按钮的 closest('[role="tablist"]') 为 null。

Summary
role="tablist"andaria-orientationfrom the outer navigation container to the element that owns the tab nodestabBarExtraContent, the add control, and overflow operations visually unchanged but outside the tablist accessibility ownershipFixes #1013.
Why
The outer navigation element currently owns arbitrary
tabBarExtraContent. When that content contains a button, accessibility tools reportaria-required-childrenbecause a tablist should own tabs rather than unrelated interactive controls. The inner-nav-listalready contains the tab nodes and remains the existing measurement/transform node, so moving only the ARIA role fixes ownership without changing layout or ref behavior.Validation
