只处理标题触发元素自身的 Space 键事件。

当 extra 包含获得焦点的按钮时，按钮的 Space 键事件会冒泡到标题容器。此处调用 preventDefault() 并切换面板，会取消按钮的默认操作。请在处理前确认 e.target === e.currentTarget，并增加嵌套按钮的回归测试。WAI-ARIA Accordion Pattern 也将 Space 键切换限定于焦点位于折叠标题的情况。(w3.org)

Review comment at @src/Panel.tsx around lines 51 - 52:
更新 Space 键处理逻辑，仅当事件目标与当前目标相同时才调用 preventDefault 并切换面板，避免 extra
中嵌套按钮的事件触发标题行为；为嵌套按钮添加回归测试，验证其 Space 键默认操作不被取消且不会切换面板。
