QQuickView::mousePressEvent() not always called on Android (but on desktop)

I've created a sub class of QQuickView that overrides mousePressEvent() like this:

void CustomViewer::mousePressEvent(QMouseEvent *event)
{
    qDebug() << "MousePress:" << event;
    QQuickView::mousePressEvent(event);
    emit interaction();
}

If run on the desktop my custom mousePressEvent() method is called whenever the mouse is pressed by the user. No matter if the user clicks inside a QQuick MouseArea or outside of it.

But if the code is run on Android, the mousePressEvent() method is only called if the user taps outside a MouseArea. If the user taps inside a MouseArea or a ListView, the method is not called at all.

Update: I see the same behavior with mouseMoveEvent() and mouseReleaseEvent(). Also touchEvent() is never called, but I think this is intentional.
