Summary

Preserve outer Dropdown Escape close/focus behavior for inline submenus while leaving popup-submenu Escape to its menu owner. Inline submenus are identified within the root menu using rc-menu's mode class suffix, including custom prefixes. Popup submenus remain deferred even when a custom popup container places them inside the root DOM.

Fixes #274. Addresses the maintainer-reported inline regression.

Validation

• Prior head fails three new inline Escape close/focus cases; three original controls pass.
• Updated complete suite: 6 suites / 38 tests / 1 snapshot pass, including an actual rc-menu inline child, wrapped/direct refs, custom prefix and popup-container controls.
• The same 38 tests pass with listener registration temporarily changed to capture, checking the regression's capture-phase dimension. This is not a full independent validation of every fix: use capture phase for keydown listener in useAccessibility #273 change.
• TypeScript, lint (0 errors / 1 existing warning), ESM/CJS/declaration/Less build and changed-file formatting pass.
• Dependencies resolved from declared ranges on Node 24.15.0 with legacy-peer-deps / lifecycle scripts disabled; no manifest or lockfile changes. No new native-browser or screen-reader run.

AI-assisted source analysis, regression tests and validation. Exact source, test outputs, signed head and remote file readbacks verified.

Summary by CodeRabbit

• 修复
  • 在弹出式子菜单中按下 Escape 时，不会关闭外层菜单或将焦点移回触发器。
  • 在根菜单或行内子菜单中按下 Escape 时，仍会关闭菜单并将焦点移回触发器。

Walkthrough

Escape 处理现在会根据事件目标所在的菜单层级决定是否关闭弹出菜单。新增测试覆盖弹出式和内联嵌套菜单，以及根菜单的关闭和焦点行为。

Changes

菜单 Escape 处理

Layer / File(s)	Summary
菜单层级判断与测试 src/hooks/useAccessibility.ts, tests/useAccessibility.test.tsx	handleKeyDown 的事件参数改为 KeyboardEvent。处理 Escape 时，若事件目标位于根菜单中的非内联子菜单，则不关闭外层菜单或移动焦点；其他情况保留原有关闭和焦点返回逻辑。测试覆盖弹出式子菜单、根菜单、内联子菜单及真实 rc-menu 行为。

Change: Bug fix

Possibly related issues

• Escape inside a focused submenu closes the entire Dropdown instead of returning to its parent item #274：该问题涉及嵌套子菜单触发 Escape 时外层 Dropdown 错误关闭，与本次修改的处理路径相关；现有摘要指出本次修改单独可能不是完整修复。

Possibly related PRs

• react-component/dropdown#273：该 PR 修改同一 Escape 监听路径的事件阶段。相关说明指出，本次子菜单判断与监听阶段变更共同影响嵌套菜单 Escape 行为。

The change is mergeable on the supplied evidence. A real popup-menu Escape test would strengthen regression coverage as a follow-up.

This guard also skips Escape for inline submenus, whose role="menu" differs from the root but whose keyboard handler does not consume Escape.

I reproduced this with a Dropdown overlay containing <Menu mode="inline" defaultOpenKeys={['sub']} ... />, with focus on a child item. The base calls onOpenChange(false) and restores trigger focus; this head does neither. The regression also persists with #273's Escape-only capture listener applied.

Could we distinguish popup submenus that handle Escape from inline submenus, preserve the latter's outer close/focus behavior, and add a regression test?

[nrps9909]

Fixed in signed/GitHub-Verified b32c80c724e5cabd39eb3d9be64b2f42933f1c67. The previous role-only guard was too broad, as you reported.

Inline mode submenus inside the root now retain outer close/focus behavior; popup submenus still defer, including with an in-root custom popup container. Added three inline regressions (two ref shapes/custom prefix plus an actual rc-menu inline child): prior source fails all three, with three original controls passing. The complete updated suite passes 38 tests / one snapshot, types, lint, compile and formatting. A temporary capture-registration variant also passes all 38 tests; the committed registration is restored. This checks the capture-phase aspect without claiming a full new #273 integration or native-browser/AT run.

Pushed with an expected-old-head lease and verified head/signature, both source blobs and updated PR body. No manifest/lockfile changes. AI-assisted fix and validation; exact source and outputs checked.

为弹出式子菜单的 Escape 关闭行为补充断言。

leaves popup nested menu Escape to its owner 的四个用例只断言外层 Dropdown 不调用 onOpenChange，并且焦点仍在子项上。它们不验证子菜单是否关闭。如果子菜单的 Escape 处理失效，这些用例仍会通过。建议在真实弹出式 Menu 的测试中，断言 Escape 后子菜单已关闭。
