Summary

• keep the picker open when a focused panel control becomes disabled
• treat the resulting blur as internal and move focus to the panel container
• add regression coverage for the disabled-target blur path

Root cause

Chrome 152 defers the blur caused by disabling the focused button. React therefore receives the blur after the DOM commit with a null relatedTarget, causing the picker to treat the focus as having left the popup.

Testing

• Full test suite: 469 passed
• TypeScript check
• ESLint
• Chrome 152.0.7977.82 browser verification

Summary by CodeRabbit

• Bug 修复
  • 修复日期选择器设置 minDate 后，点击上一页按钮可能导致焦点异常的问题。
  • 当面板中的控件因限制变为禁用状态时，焦点会保持在选择器面板内，选择器不会意外关闭。
  • 优化失焦处理，确保相关失焦事件正常触发，同时避免不必要的整体失焦行为。

Walkthrough

本次变更调整面板禁用控件的失焦处理。相关测试验证 minDate 限制下的前一页按钮状态、onBlur 触发、面板焦点转移和选择器打开状态。

Changes

面板焦点与日期边界

Layer / File(s)	Summary
禁用面板控件的失焦处理 src/PickerInput/hooks/useFocusEvents.ts, tests/picker.spec.tsx	当面板失焦目标带有 disabled 属性时，onFieldBlur 恢复当前目标焦点，并跳过整体失焦处理。测试验证日期边界下的按钮禁用、onBlur 触发、面板焦点和选择器状态。

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to e4e07

The picker now preserves internal focus and remains open when a navigation control becomes disabled at a date boundary, with regression coverage for the affected blur path. No current merge-blocking risk remains.

Poem

小兔检查面板边界，
禁用按钮安静停歇。
焦点回到容器里面，
失焦事件清晰可见。
选择器继续睁着眼。

🌐 Web query:

MDN ShadowRoot activeElement document.activeElement shadow host

💡 Result:

When an element inside a shadow tree is focused, the behavior of activeElement depends on whether you are querying the document or the shadow root [1][2]. 1. Document.activeElement: When focus is inside a shadow tree, document.activeElement returns the shadow host (the custom element containing the shadow root) rather than the specific element that has focus [2][3][4]. This behavior is designed to prevent leaking internal shadow DOM details to the main document context [5]. 2. ShadowRoot.activeElement: The ShadowRoot interface has its own activeElement property, which returns the element within that specific shadow tree that has focus [1]. If no element within that shadow tree is focused, it returns null [1]. To find the "deepest" active element—the actual element focused, even if nested inside multiple shadow roots—you must recursively traverse the shadow roots [6][3][4]. Example of recursive function to find the deeply focused element: function getDeepActiveElement { let activeElement = document.activeElement; while (activeElement && activeElement.shadowRoot && activeElement.shadowRoot.activeElement) { activeElement = activeElement.shadowRoot.activeElement; } return activeElement; } This approach drills down through shadow roots until it reaches an element that either does not have a shadow root or does not have a focused element within its shadow root [6][3][4].

修正 ShadowRoot 下的焦点判断

当 PickerPanel 位于 ShadowRoot 内时，document.activeElement 返回 shadow host，而不是当前按钮。边界导航后，activeNavigationRef 不会记录按钮，焦点也不会移到面板。请读取当前按钮所属根节点的 activeElement，并增加对应回归测试。

你应该直接在 onBlur 事件监听一下 blur 的对象是否有 disabled 的 attr，如果有就说明不是外部失焦，不用关闭就好了
