鼠标在OwnerData/CustomDraw模式ListView上无WM_MOUSEMOVE消息的问题

当鼠标位于启用LVS_OWNERDATA（OwnerData）及CustomDraw模式的ListView控件上方时，主窗口无法收到WM_MOUSEMOVE消息，但鼠标在窗体其他区域时可正常接收该消息。

编辑记录1：子类化方案尝试 #

最初使用SetWindowLong进行ListView子类化：

bool toggle = false;
WNDPROC original_procedure;
LRESULT CALLBACK ListViewWndProc(HWND ws, UINT Message, WPARAM wParam, LPARAM lParam) {
    switch (Message) {
        case WM_MOUSEMOVE: if (!toggle) { printf("LV Mouse move\n"); toggle = true; } break;
        case WM_MOUSELEAVE: if (toggle)  printf("LV Mouse Leave\n"); break;
        case WM_MOUSEHOVER: if (toggle) printf("LV Mouse hOver\n"); break;
    }
    return CallWindowProc(original_procedure, ws, Message, wParam, lParam);
}

在WM_CREATE中调用：

original_procedure = (WNDPROC)SetWindowLong(hwndListView, -4/*GWL_WNDPROC*/, (long)ListViewWndProc);

该方式对ListView无效，替换为SetWindowLongPtr后可正常捕获ListView的鼠标消息。

编辑记录2：SetCapture方案尝试 #

在WM_CREATE中调用SetCapture(hWnd)，可让主窗口WndProc收到正确的WM_MOUSEMOVE消息，但窗口最小化/最大化后，捕获状态失效，无法继续接收ListView区域的鼠标消息。
