pinchfinished event is not received on tapping a finger while pinch is ongoing.

I have a flickable which contains a pinchArea.

PinchArea {
id: pinchArea
MouseArea
{
id: mouseArea
onClicked:

anchors.fill: parent
}
onPinchStarted:
{
}
onPinchFinished:
{
}
}

When the pinchUpdate is happening, if I remove one of my fingers and tap, I do not get a pinchfinished event (even after removing the second finger!)
