DragHandler in a Controls 2 Button: can't click the button

XMLWordPrintable

      import QtQuick 2.0
import Qt.labs.handlers 1.0
import QtQuick.Controls 2.2

ApplicationWindow {
    visible: true
    width: 200; height: 200
    Button {
        width: 100; height: 50
        text: "Drag me"
        onClicked: console.log("clicked")
        DragHandler { }
    }
}

      The initial problem occurs in 

      void QQuickWindowPrivate::deliverMatchingPointsToItem(QQuickItem *item, QQuickPointerEvent *pointerEvent, bool handlersOnly) {
    ...
     if (pointerEvent->allPointsAccepted() && !pointerEvent->isReleaseEvent()) 
        return;
    ....
}

      That is, if the DragHandler is interested, it does a passive grab and accepts the eventpoint. (Shouldn't it?) And then we don't deliver to the Button. So maybe it should check allPointsGrabbed() instead. Well, if I do that, then we have the opposite problem: the Button grabs, and the DragHandler doesn't get updates, despite having a passive grab.

      So again this proves that we need to make it deliver to passive grabbers regardless of the exclusive grab, IMO.
