Miikka Heikkinen 7bc576771d Fix sending simulated keyboard events to popup widgets
Popup widgets steal the keyboard grab stealthily without it being
visible via QWidget::keyboardGrabber(). To more accurately simulate a
real keyboard event, prioritize sending simulated keyboard events to
the active popup widget over QGuiApplication::focusWindow().

Task-number: QTBUG-24326
