    Description

      Do a 2-finger drag on touch pad. Don't flick ie. make sure to stop the movement before releasing. When you lift your fingers, Flickable does not emit movementEnded() and the value of the moving property stays true.

      import QtQuick 2.5
import QtQuick.Window 2.2

Window {
    width: 360
    height: 520
    visible: true

    ListView {
        model: 100
        anchors.fill: parent
        delegate: Text { text: index }
        onContentYChanged: console.log("onContentYChanged", contentY)
        onMovementStarted: console.log("onMovementStarted")
        onMovementEnded: console.log("onMovementEnded")
        onMovingChanged: console.log("onMovingChanged", moving)
    }
}

      If you have for example a ScrollIndicator from QQC2 attached to the Flickable, the indicator does not hide since it thinks the content is moving.

      Reproducible with the latest released pre-built versions of Qt 5.6 and Qt 5.7, and the latest qt5 5.7 branch.
