📝 Problem

When a Trigger with unique is unmounted while its shared popup is open, the popup stays on screen forever (until another tooltip shows up). Reported in ant-design/ant-design#59603 with ConfigProvider tooltip={{ unique: true }} + antd Tooltip.

Two issues combined:

  1. Trigger has no unmount cleanup, so nothing tells UniqueProvider to close the shared popup when its target goes away.
  2. In non-controlled mode triggerOpen delegates open state entirely to the provider, so the frozen isOpen() of an unmounted trigger keeps reporting stale value, which makes the isOpen guard in hide unreliable.

🔧 Solution

  • Add a release(target) method to UniqueContext. On unmount, Trigger calls release(targetEle); the provider closes the popup only when it is currently showing for that exact target, so unmounting an inactive trigger never closes someone else's popup.
  • In hide, skip the isOpen guard when the current target is already disconnected from the DOM (isConnected === false), since its trigger must be gone. This also matches the documented intent of useTargetState ("When target is removed. Do hide the popup.").

🧪 Test

  • should hide popup when the trigger is unmounted: hover to open → unmount the trigger → popup should be hidden (red before this PR).
  • should not hide popup when an inactive trigger is unmounted: popup opened by trigger A stays open when inactive trigger B unmounts.

Walkthrough

唯一弹层 provider 现在跟踪最近触发目标,并支持释放目标。触发器卸载时会通知 provider。新增测试覆盖活动和非活动触发器的卸载行为。

Changes

唯一弹层释放

Layer / File(s) Summary
Provider 目标跟踪与释放
src/context.ts, src/UniqueProvider/index.tsx
上下文新增 release(target)。provider 记录最近触发目标;hide 会检查目标是否仍连接到 DOM。目标匹配且弹层打开时,release 会关闭弹层。
触发器卸载清理与测试
src/index.tsx, tests/unique.test.tsx
触发器卸载时会释放其保存的目标。测试验证卸载活动触发器后弹层隐藏,卸载非活动触发器后弹层保持显示。

Merge Risk: 🟡 Moderate · up to adf32

Closing a shared popup when its trigger unmounts works in the main case. In hover-delay and dynamic-prop scenarios, the wrong popup can be closed, a popup can open for an already unmounted trigger, or the popup can stay open. These should be fixed or explicitly accepted before merging.

让卸载清理读取最新的 unique 状态。

unique 是可变的公开属性。若组件初始为 false,之后改为 true,空依赖数组的 effect 不会注册清理函数。此后触发器可以调用 uniqueContext.show,但卸载时不会调用 release,共享弹层可能继续显示。

不要直接把 uniqueContext、unique 和 parentContext 加入依赖数组。依赖变化也会执行 effect 清理,而 targetEleRef.current 仍可能指向一个尚未卸载的目标。此时调用 release 会错误地关闭仍属于该目标的弹层。请保持 effect 仅在卸载时清理,并通过 ref 读取最新状态。

区分已显示目标与待显示目标。

当 A 的弹层已打开,而 B 调用 show 并等待延迟时,targetRef.current 立即变成 B,但弹层仍属于 A。如果此时卸载 B,release(B) 会因 open 为 true 而关闭 A 的弹层。即使 A 是保持 popupVisible={true} 的受控触发器,这次卸载也会错误地隐藏 A。请在实际调用 trigger(showOptions) 时记录已显示目标,并单独跟踪待显示目标。

在 release 中取消匹配目标的延迟 show。

Trigger 卸载时会调用 uniqueContext.release(targetEleRef.current)。但延迟 show 由仍挂载的 UniqueProvider 的 useDelay 持有。当前 release 仅在 open 为真时关闭弹层;mouseEnterDelay 尚未结束时,open 为假,待执行回调不会被取消。该回调随后仍可为已卸载的目标调用 trigger(showOptions) 并打开弹层。

请让 useDelay 暴露取消当前定时器的能力,并在目标匹配时先取消待执行回调,再保留现有的关闭逻辑。
