	// ==================================================================
	// 【诊断 · 新建商品弹框「输入文字消失」（Win10 触摸键盘）】
	//
	// 现象：手指点触摸键盘输入，已输入的字（尤其中文输入的组合串）会消失；
	//       鼠标点同一个键盘则完全正常。
	//
	// 已确认的代码事实（不用日志就能确定的）：
	//   · 文本**真实存放**在 CEditWnd —— 一个原生的 EDIT 子窗口里（WS_CHILD），
	//     DuiLib 只通过 EN_CHANGE 把内容同步回 CEditUI::m_sText；
	//   · 该窗口的生命周期**极短**：只要它失去键盘焦点，
	//     CEditWnd::OnKillFocus 就会 PostMessage(WM_CLOSE) **把它销毁**；
	//   · 所以"谁在这一刻抢走了焦点"就是本问题的全部答案。
	//     一旦焦点离开 EDIT，输入法正在拼的字会被撤销（中文尤其明显），
	//     之后到达的字符也无处可去 —— 用户看到的就是"输入完被自动删除"。
	//
	// 因此下面这几个 helper 只做一件事：把"抢焦点的是谁"记清楚。
	// 判读要点：
	//   · 若 EDIT-KILLFOCUS 的 newTid != selfTid ⇒ 焦点被**别的进程/线程**抢走
	//     （触摸键盘 TabTip / TextInputHost 是首要嫌疑）；
	//   · newClass 是 "#32770" ⇒ 被我们自己的弹框拿走了；
	//   · 若同一个 owner 出现 INIT → FIN → INIT 的抖动 ⇒ 窗口在反复重建，
	//     重建时用的是 m_sText（可能落后于 IME 的组合状态）⇒ 字就"没了"。

	//
	// 背景（真机日志实证，一次"手指点输入框"就够看清楚）：
	//
	//   PTR-DOWN stealFocus      ::SetFocus(m_hWndPaint)        ← UIManager.cpp 抢走键盘焦点
	//   EDIT-KILLFOCUS           PostMessage(WM_CLOSE)          ← 销毁请求**排队**（异步）
	//   EDITUI-SETFOCUS 复用编辑窗  ::SetFocus(hEdit)            ← 焦点已经还给 EDIT
	//   …… 几十毫秒后 ……
	//   EDIT-FIN                 窗口还是被那条排队的 WM_CLOSE 销毁了
	//
	// 也就是说：**焦点刚被抢回来，窗口照旧死掉**。而 CPaintManagerUI::SetFocus 有
	// `pControl == m_pFocus` 早退，不会再发 UIEVENT_SETFOCUS ⇒ 窗口不再重建。
	// 触摸键盘敲出的字符、退格、输入法候选词的提交，就全都失去了落点
	// （真机日志里对应"9.7 秒零条 EDIT-CHANGE"）。
	//
	// "手指点虚拟键盘"之所以必现、鼠标不犯，是因为手指点它的那一刻本窗口会短暂失活
	// （WND-ACTIVATE wParam=0(INACTIVE) fg=00000000 + EDIT-KILLFOCUS newFocus=00000000），
	// 于是又排上一条 WM_CLOSE；鼠标那一路不会走到这里。
	//
	// ⇒ 判据（纯状态、零时间戳）：**延后到 WM_CLOSE 真正被取出来处理时**，再看一眼
	//   「我的 owner 现在还是不是 DuiLib 的焦点控件」：
	//
	//     · 还是 ⇒ 这次失焦只是**瞬态**（窗口内部焦点搬家 / 本窗口短暂失活），
	//              owner 还要接着输入 ⇒ 取消销毁，窗口活着等 SETFOCUS 回来；
	//     · 不是 ⇒ 焦点已被别的控件/别的窗口拿走，或者控件被隐藏/移除、弹框正在销毁
	//              （那些路径都会先 SetFocus(NULL) 或把 m_pFocus 置 NULL）
	//              ⇒ 按原设计销毁。
	//
	// 为什么必须延后：CPaintManagerUI::SetFocus 的顺序是
	// 「先 ::SetFocus(画布窗口) 让旧编辑窗失焦 → 再派发 KILLFOCUS → 最后才把 m_pFocus 换成新控件」。
	// 若在原生 WM_KILLFOCUS 里当场判断，读到的一定还是**旧值** ⇒ 区分不了
	// "瞬态失焦"和"真的切到另一个控件"。
	//
	// 这条判据对"窗口失活"同样成立 —— 而窗口失活恰恰是手指点触摸键盘时唯一会发生的变数。
