[REG: 5.11->5.12.0] :QGestureEvent not grabbed on Android

I created MyGraphicsView class that inherits QGraphicsView and made it grab TapAndHoldGesture by doing:

grabGesture(Qt::TapAndHoldGesture);

It is expected that dialog box says "QTapAndHoldGesture captured." when you long tap on Graphics View.

It works with Qt 5.11.3 but not with 5.12.

Is seems QGestureEvent does not comes to MyGraphicsView at all.
