PressDelay on QML Flickable doesn't work

[aabc]

I try to use pressDelay on QML Flickable but for some reason it doesn't work.
Has anyone try it ?

This works for me, both QtQuick 1 and 2:
@
Flickable {
id: root
width: 200; height: 200
contentHeight: 600
pressDelay: 500
Rectangle {
width: 50; height: 50
color: ma.pressed ? "blue" : "green"
MouseArea {
id: ma
anchors.fill: parent
}
}
}
