Windows: Application does not receive single-touch events, crash on multi-touch

To reproduce:

• Make sure touch screen is disconnected
• Start any Qt Quick application, for example Calendar example
• Attach touchscreen
• Tap on controls of the application, nothing happens

Trying to scroll or zoom with 2 fingers will cause a crash. Debug version will catch assert in (qwindowsmousehandler.cpp QWindowsMouseHandler::translateTouchEvent()):

Q_ASSERT(m_touchDevice);

If that would be created, it will then fail in:

Q_ASSERT(QWindowsContext::user32dll.getTouchInputInfo);
