避免一次焦点转移触发两次 onFocus。
当 <li> 本身获得焦点且包含 a[href] 时，处理器会先调用 onFocus，再聚焦链接。链接的焦点事件会冒泡到同一处理器，并再次调用 onFocus。请跳过 <li> 焦点事件上的回调，让链接的焦点事件只通知调用方一次。

I reviewed exact head 6fc01b8b9a62446e38664c0b982b7957de9d5b6b, base 8dfdef453a24cee1bda115e3249b17289356829d, and GitHub merge preview 4df8100043f66cb2fd3901419355063822274004 (both parents verified).
The original first-focus/link activation problem is fixed: native Chrome Enter follows the focused link on head/preview, while base stays on the li and does not navigate. ArrowDown, Home/End, disabled-first-item skipping, controlled active-key focus, and plain-item fallback also work in the tested cases.
Two behavior regressions need attention before merging: native Enter now dispatches item/menu callbacks twice from ref focus (and cancels selection in multiple mode), and direct item focus loses preventScroll. The inline comments contain exact steps and base/head results.
Local validation on Node 24.15 / React 19.3: complete base 13 suites / 144 tests / 20 snapshots; head and preview each 13 / 146 / 20. Both added focus tests fail when copied to base; existing controls pass. Head TypeScript, compile, and lint pass (0 errors / 11 warnings). Browser evidence uses real Chrome 154.0.8037.98 and native key events. These local results do not establish remote CI success, screen-reader behavior, or complete WCAG conformance.
AI assistance disclosure: Codex helped inspect the source, prepare/run the isolated tests and Chrome probe, and draft this review. No upstream source patch or duplicate PR was created.

[P2] Handle native anchor Enter without also invoking legacy keyboard activation
Changing initial/ref focus from the li to its anchor exposes the native Enter click to MenuItem.onInternalKeyDown, which already calls both onClick and onItemClick. Chrome then dispatches the anchor's native click, invoking both callbacks again. With multiple, one Enter selects and immediately deselects the same item.
Reproduction on this exact head and merge preview: render <Menu multiple ref={ref} items={[{ key: 'first', label: <a href="#destination">Link</a> }]} onClick={spy} />, call ref.current.focus(), and press Enter with a real keyboard driver. The spy records keydown, then click, and no item remains selected. Base records one keydown and leaves one selected item (but has the original missing navigation bug).
The same double-activation already exists on base after arrow navigation focuses an anchor; this PR additionally exposes it on first/ref focus. Please let native anchor activation happen once while retaining legacy Enter activation for non-link items, and cover both paths plus multiple selection with native-key tests.

[P2] Preserve the caller's scroll decision when redirecting item focus
The extra link.focus() starts a second focus operation with default scrolling. A caller using the public ref.current.findItem({ key: 'first' }).focus({ preventScroll: true }) can therefore no longer keep the viewport in place when that item contains a link.
In a real Chrome page with the menu below the viewport (top 1600px), starting at scrollY=0, base keeps scrollY=0; this head and the merge preview jump to scrollY=1267. Direct focus also invokes the item's onFocus twice (li, then anchor), rather than once on base. MenuRef.focus({ preventScroll: true }) still preserves scrolling because it passes the option directly to the anchor.
Please preserve the initial focus operation's scroll decision during this redirection (for example, prevent scrolling on the secondary focus) and add coverage for direct item focus with preventScroll, alongside the existing MenuRef focus test.

Summary
Follow-up to the discussion in ant-design/ant-design#59445, where
@yoyo837suggested solving keyboard focus delegation upstream in@rc-component/menu:Problem
Previously, arrow-key navigation in
useAccessibility.tsplaced DOM focus on an inner<a>if present. However, initial/ref focus (menuRef.current.focus()) and directMenuItemfocus placed DOM focus on the<li>element. This inconsistent behavior meant that when entering the menu,Enterkeypresses did not trigger anchor navigation because the<a>element lacked native DOM focus.Scope Covered
